backIntroduction
The National Institute of Genetics (NIG) was established in 1949 as the central institute to
study various aspects of genetics. It was reorganized in 1984 as an inter-university research
institute to promote collaborations with researchers at universities. Since 1988, NIG has been
participating in graduate education as the Department of Genetics of the Graduate University
for Advanced Studies (SOKENDAI). NIG also serves as a center for various genetic
resources such as mutant strains, clones and vectors, and houses DDBJ, the DNA Data
Bank of Japan, and a DNA sequencing center.
The history of NIG overlaps the period of a revolution in the field of life science. Genetics is
no longer a discipline to study the rules and mechanisms of heredity, but has become thebasis for all fields of life science. Molecular techniques now allow us not only to decipher theentire genome sequence of organisms including humans, but also to understand the detailsof higher biological phenomena: cell differentiation, morphogenesis, brain function, andevolution --- the history of life itself. Currently, 36 research groups are actively performing
pioneering and cutting-edge researches in these fields at NIG.
Recent generation of massive information on biological systems and their environment
calls for new directions in life sciences, such as bioinformatics, system-level analysis, andtheoretical approaches to extract knowledge from databases. To this end NIG and three othernational institutes, the National Institute of Informatics, The Institute of Statistical Mathematics
and the National Institute of Polar Research have formed a new organization, the Research
Organization of Information and Systems (ROIS) since April 2004, as a part of the reform ofnational universities and research institutes in Japan. Inter-institutional collaborations within
the new organization are in progress.
We welcome your comments and suggestions on our research activities and endeavors.

Identification and characterization of the CENP-H-I complex proteins in higher
vertebrate cells.
Masahiro Okada, Tetsuya Hori, Mi-Sun Kwon, Aussie Suzuki, Mayumi Takahashi, andTatsuo Fukagawa
The centromere plays a fundamental role in accurate chromosome segregation duringmitosis and meiosis in eukaryotes. Its functions include sister chromatid adhesion andseparation, microtubule attachment, chromosome movement and mitotic checkpoint control.
Although chromosome segregation errors cause genetic diseases including some cancers,
the mechanism by which centromeres interact with microtubules of the spindle apparatus
during cell division is not fully understood.
To understand the function of the centromere, we were led to develop a genetic method thatutilizes the hyper-recombinogenic chicken B lymphocyte cell line DT40. The high level ofhomologous recombination in DT40 cells permit efficient targeted disruption of genes ofinterest. We have improved this system and have created several cell lines with conditional
knockouts of several centromere proteins to investigate the molecular mechanism ofcentromere assembly and function. We have proposed a model for kinetochore assembly invertebrate cells (Fukagawa et al., EMBO J., 2001; Nishihashi et al., Dev. Cell, 2002;
Fukagawa, Exp. Cell Res., 2004; Regnier et al., Mol. Cell. Biol., 2005; Mikami et al., Mol.
Cell. Biol., 2005). In this model we explained that many unidentified proteins could be
involved in kinetochore assembly. Therefore, we tried to identify new centromere proteinsthat associate with CENP-H or CENP-I using the proteomics approach. We prepared DT40
cell lines in which expression of CENP-H was replaced by expression of CENP-H-Flag or
CENP-H-GFP (Mikami et al., Mol. Cell. Biol., 2005). We also prepared DT40 cell lines inwhich expression of CENP-I was replaced by expression of CENP-I-Flag or CENP-I-GFP.
We extracted chromosome fraction from these cell lines and performed
immunoprecipitation with anti-Flag or anti-GFP antibodies. Proteins co-precipitated with
antibodies were analyzed by mass spectrometry, and we identified several polypeptides
and cloned the corresponding cDNAs. As we confirmed that these proteins constitutively
localize to centromeres in DT40 cells, we named them CENPs. We also performed
immunoprecipitation experiments with human cells and identified similar proteins. In total,
our purifications in chicken and human cells identified 11 interacting proteins (CENP-K,
CENP-L, CENP-M, CENP-N, CENP-O, CENP-P, CENP-Q, CENP-R, CENP-50 (U),CENP-H and CENP-I) that localize constitutively to centromeres as components of the
CENP-H-I associated complex. Our analysis of these proteins using chicken DT40
knockouts and RNAi analysis in human cells demonstrates that the CENP-H-I complex canbe divided into three functional sub-complexes, each of which is required for chromosomealignment and faithful chromosome segregation. Interestingly, newly expressed CENP-A is
not efficiently incorporated into centromeres in knockout mutants of a subclass of CENP-H-I
complex proteins, indicating that the CENP-H-I complex may function in part as a markdirecting CENP-A deposition to centromeres.
Functional analysis of CENP-O-class proteins that are required for recovery fromspindle damage.
Tetsuya Hori, Masahiro Okada, Tomoko Motohashi, Kazuko Suzuki, and Tatsuo Fukagawa
We previously identified a multi-subunit complex (CENP-H/I complex) at kinetochores fromhuman and chicken cells. We showed that the CENP-H/I complex can be divided into threefunctional classes. Among them, we investigated CENP-O class-proteins, which include
CENP-O, -P, -Q, -R, and -50 (U). We created chicken DT40 cell knockouts of each of these
proteins and found that all knockout lines were viable but showed slow proliferation andmitotic defects. Phenotype analysis showed that all proteins except for CENP-R wererequired for recovery from spindle damage. Kinetochore localization of CENP-O, -P, -Q,
and -50 was interdependent, but kinetochore localization of these proteins was observed in
CENP-R-deficient cells, and CENP-R localization was abolished in CENP-O, -P, -Q, or -50
knockouts. A coexpression assay in bacteria showed that CENP-O, -P, -Q, and -50
proteins form a stable complex, which can associate with CENP-R. These results indicatethat CENP-O-class proteins are tightly associated, and this complex contributes tokinetochore function.
Although the CENP-50 knockout was not lethal at cellular level, it is interesting to investigate
function of CENP-50 at individual level. Therefore, we are making and characterizing
knockout mice of CENP-50. We also discovered that expression of a brain specific gene
was reduced in CENP-50-deficient cells.
Functional analysis of the CENP-C complex, which associates with the Mis12
complex.
Mi-Sun Kwon, Masahiro Okada, Tetsuya Hori, and Tatsuo Fukagawa
CENP-C is a conserved inner kinetochore component. To understand the precise roles of
CENP-C in the kinetochore, we created a cell line with a conditional knockout of CENP-C
with the tetracycline-inducible system, in which the target protein is inactivated at the level oftranscription. We found that CENP-C inactivation causes mitotic delay. However,observations of living cells showed that CENP-C-knockout cells progressed to the next cell
cycle without normal cell division following mitotic delay. Interphase cells with two nuclei
before subsequent cell death were sometimes observed. We also found that ~60% of
CENP-C-deficient cells had no Mad2 signals even after treatment with nocodazole,suggesting that lack of CENP-C impairs the Mad2 spindle checkpoint pathway. We also
observed significant reductions in the signal intensities of Mis12 complex proteins at
centromeres in CENP-C-deficient cells. CENP-C signals were also weak in interphasenuclei but not in mitotic chromosomes of cells with a knockout of CENP-K, a member of
CENP-H complex proteins. These results suggest that centromere localization of CENP-C
in interphase nuclei occurs upstream of localization of the Mis12 complex and downstreamof localization of the CENP-H complex (Kwon et al., Mol. Bio. Cell in press).
Functional roles of Ago family proteins in verterbrate centromeres
Tomoko Motohashi, and Tatsuo Fukagawa
RNAi-mediated silencing of gene expression occurs when double-stranded RNAs
(dsRNAs) are cleaved by Dicer into 21- to 23-nt small interfering RNAs (siRNAs). ThesesiRNAs guide a multicomponent nuclease, RNA-induced silencing complex (RISC), todegrade specific mRNAs. Although the Dicer-mediated gene-silencing is evolutionarily
conserved system, the biological functions of the RNAi machinery are not fully understood.
Genetic strategies have been used to examine the biological functions of the RNAi
machinery in C. elegans, Arabidopsis, Drosophila and fungi. There are also many reportsthat the RNAi machinery via RNA-induced initiation of transcriptional silencing (RITS)
complex is related to heterochromation formation and chromosome segregation in fission
yeast. However, it was unclear whether the RNAi machinery is associated with chromosome
segregation in vertebrate cells. To examine the biological function of the RNAi-related
pathway in vertebrate cells, we generated and characterized a conditional loss-of-function
mutant of Dicer in a chicken-human hybrid DT40 cell line that contains human chromosome
21 (Fukagawa et al, Nature Cell Biol., 2004). Loss of Dicer leads to cell death withaccumulation of abnormal mitotic cells that show premature sister chromatid separation.
Aberrant accumulation of transcripts from α-satellite sequences, which consist of humancentromeric repeat DNAs, was detected in Dicer-deficient cells. We then started to
examine expression profile of non-coding region using high-density DNA-microarray, when
expression of Dicer was lost. We identified several non-coding RNAs from this method. We
are characterizing biological function these RNAs. We also created conditional knockout
cells for other components involved in RNAi machinery such as Ago-family proteins.
Phenotype analyses of Ago-deficient cells were started. We found several genes whose
expression are increased or decreased upon Ago knockouts. We are characterizing thesegenes how these are related to functions of Ago family proteins.

Replication factor required for centromeric structures and functions in fission
yeast.
T. Natsume, Y. Tsutsui, H. Iwasaki and F.Yamao
The chromatin is assembled into a various higher order structures that are essential for its
functional regulation and expression. It is maintained via a variety of the post-translational
modifications. The preservation of the chromatin structure during duplication of thechromosome is another aspect of the epigenetic inheritance of the structural information. To
address this issue, we focused a replication factor, the dysfunction of which caused defectin chromosomal integrity shown in chromosomal segregation and heterochromatin
maintenance as well as those in DNA replication and damage repair.
Fission yeast Mcl1, a conserved protein through mammalian cells, strongly interacts with
Swi7, a largest subunit of DNA polymerase a, and factors involved in processing of Okazaki
fragment, suggesting that Mcl1 is concerned with lagging strand DNA synthesis. Cells
mutated in mcl1 gene show premature separation of sister centromeres, indicating that
Mcl1 is required for sister chromatid cohesion (SCC), especially in centromere region. As
SCC depends on the heterochromatin structure, the possible involvement of Mcl1 in the
integrity of heterochromatin was examined by the alleviation of transcriptional silencing on
the spot. The gene silencing in three typical heterochromatin regions in fission yeast,
centromere, telomere regions and mating type locus, were all disrupted. However, Swi6
protein, a HP1 homologue in fission yeast, was still associated in the heterochromatin
regions. Thus, Mcl1 seems to function in Swi6-independent pathway in maintaining
heterochromatin structure. Coincidently, mcl1 and swi6 mutations showed synergistic
sensitivity to TBZ, an inhibitor of microtubule attachment to kinetochore.
mcl1 as well as swi7 mutation caused sensitivity to histone deacetylase inhibitor,
implicating the involvement of Mcl1 in HDAC-related processes. This was confirmed by theaccumulation of acetylated histone H4 at the outer centromere region as well as mat locus
and telomere region. Interestingly, in mcl1 mutant cells, the acetylated histone H4
accumulated in not only outer centromere but also central kinetochore domains. The
transcriptional silencing was deficient in the central domain of centromere. Thus, Mcl1
seems to be required for integral maintenance of kinetochore structure and function. Indeed,in mcl1 mutant cells, unequal chromosomal segregation was frequently observed. A
specific structure of at the central domain of centromere was disrupted, and association ofcentral domain- specific SpCENP-A protein to kinetochore was abolished in mcl1 mutant
cells.
Mcl1 seems to play a pivotal role in kinetochore structure and function through histone
acetylation on the spot though the precise processes are sill unclear. Most interestingly,however, these processes are likely linked with DNA replication machinery, providing anovel insight into mechanism of epigenetic inheritance of chromosomal structures.

RESEARCH ACTIVITIESOne feature of organisms is the ability to adapt to the environment. Thanks to this ability,
organisms could survive on the earth in changeable conditions. Such an ability is supported
by flexibility of the genome. On the other hand, the genome determines the design of life.
Therefore, changing of genomic information, if it occurs randomly, is likely to be toxic fororganisms. Indeed, it is known that genomic instability causes cancer and prematuresenescence. We are studying how cells change the genome safely. One attractive
mechanism for this change is gene amplification. Gene amplification makes it possible tocreate new genes and modify them without destroying the original one.
We have been analyzing amplification of the ribosomal RNA gene repeats (rDNA) as amodel system.
(1) Mechanisms to maintain the stability of rDNA
-Analysis of the relationship between replication and gene amplificationAusten R.D. Ganley, and Takehiko Kobayashi
The ribosomal RNA gene repeats (rDNA) is one of the most characteristic regions ineukaryotic chromosomes. The repeats consist of more than 100 tandem units occupying
large regions of the chromosome(s) in most organisms. Cells are known to deal with this“unusual domain” in a unique manner. In particular, repeated genes families such as rDNA
are one of the most fragile sites for deletional recombination. Even though the rDNA issusceptible to this kind of instability, each organism is known to maintain a specific repeat
copy number of rDNA, thereby indicating the presence of a mechanism for maintenance of
copy number. We have been studying this mechanism and found a unique amplification
system that uses replication fork blocking activity. The replication fork barrier site (RFB)
inhibits the replication fork and causes DNA double strand breaks (DSBs). These DSBs
are then repaired by recombination. If the broken end recombines with an unequal sisterchromatid, some copies are replicated twice and the copy number increases. In this way,
amplification takes place.
In the above “RFB-dependent rDNA amplification model”, replication initiation is also
expected to affect RFB activity and change the amplification rate. In fact, replication origins
are often found in mammalian repeated genes such as DHFR and c-myc. These

observations suggest a strong relationship between replication origins and gene
amplification, though there is no direct evidence for this.
To address this relationship, we used a yeast strain that has two rDNA copies instead of theusual wild-type 150 copies. In this strain we modified the replication origin sequence tochange its efficiency and monitored the amplification rate. We found that reduced
replication initiation resulted in reduced amplification.
It is also known that rDNA recombination produces circular DNA molecules called ERC(extrachromosomal rDNA circles). ERC accumulation promotes cellular aging. We lookedat the effect of rDNA replication initiation-modification on ERC production and found thatthese modifications change ERC number. Now we are analyzing the mechanism.
(2) Evolutionary study of repetitive genes-Analysis of concerted evolution in the ribosomal DNA repeatsAusten R.D. Ganley and Takehiko Kobayashi
Repeat families within genomes are often maintained with similar sequences. Traditionally
this has been explained by concerted evolution, where repeats in an array evolve “inconcert” with the same sequence by continual recombination between the repeats. Anotherform of evolution, birth-and-death evolution, can also explain this pattern, although in thiscase selection is the critical force. The level of intragenomic variation is the key difference
between these two forms of evolution. The huge size and repetitive nature of large repeat
arrays have made it difficult to determine the total level of intragenomic variation, so there islittle evidence to support concerted evolution over birth-and-death evolution for many large
repeat arrays.
We used whole genome shotgun sequence data from five fungal species genome projects
to show total levels of sequence variation within the ribosomal RNA gene repeats (rDNA).
The level of sequence variation was remarkably low. Furthermore, the polymorphisms thatwere detected were not functionally-constrained and exist beneath the level of selection.
These results suggest the rDNA is evolving via concerted evolution. Comparisons with arepeat array undergoing birth-and-death evolution provide a clear contrast in the level of
repeat array variation between these two forms of evolution, confirming that the rDNA does
evolve via concerted evolution. These results suggest that concerted evolution is very rapid
and efficiently maintains highly-similar repeat arrays.

RESEARCH ACTIVITIESWe have been studying on eukaryotic chromosomal DNA replication and its regulation by
the cell cycle. For this purpose, we have employed budding yeast, Saccharomyces
cerevisiae, as a model system of eukaryotic cells. Using strong genetics of budding yeast,
we have identified novel factors involving in chromosomal DNA replication and revealed
their functions in chromosomal DNA replication.
(1) CDK targets in the initiation of DNA replication
Seiji Tanaka, Toshiko Umemori, Kazuyuki Hirai, Sachiko Sakamoto and Hiroyuki Araki
Cyclin-dependent kinase (CDK) is essential in the initiation of chromosomal DNA
replication in eukaryotes. Although yeast Sld2 is known as an essential target, its
phosphomimetic form alone does not confer DNA replication in the absence of CDK
activity. We show that a JET1 mutation of CDC45 or high copy DPB11, in combination withthe phosphomimetic form of Sld2, confers CDK-independent DNA replication. Sld3, whichassociates with Cdc45, is phosphorylated by CDK and then binds to the N-terminal pair of
BRCT domains in Dpb11, which has two pairs of tandem BRCT domains. Cdc45 enhances
this binding, and the JET1 mutation as well as high copy DPB11 bypasses the requirementof Sld3 phosphorylation. Because phosphorylated Sld2 binds to the C-terminal pair of
BRCT domains in Dpb11, we argue that when CDK phosphorylates the replication proteins,
Sld2 and Sld3, two pairs of BRCT domains in Dpb11 connect them to initiate DNA
replication.
(2) The pre-Landing complex of replication proteins formed in a CDK-dependent
manner
Sachiko Sakamoto, Kazuyuki Hirai, Yoichiro Kamimura, and Hiroyuki Araki
As described above, we revealed that the interactions between Dpb11 and phosphorylated
Sld2 and Sld3, promotes the initiation of DNA replication. However, we do not know how
these interactions promotes the initiation step of DNA replication. At replication origins ineukaryotes, the pre-Replicative Complex (pre-RC) forms from late M to G1 phases in theabsence of CDK (Cyclin-dependent kinase) activity and other replication proteins including
DNA polymerases assemble when CDK activity increases from G1/S boundary. We havefound that a complex containing at least four replication factors, Dpb11, Sld2, GINS and Polε, is formed in a CDK-dependent dependent manner. To elucidate how this complex isformed, we purified these factors to near homogeneity and examined whether they interact
each other in vitro. It is revealed that they bind each other and form a complex in vitro. This
result suggests that they can form a complex without any other factor. Thus, this complex

formation is one of the key steps to promote the initiation of DNA replication.
(3) Functional analysis of Sld7
Tamon Tanaka and Hiroyuki Araki
sld7 was isolated as a novel sld (synthetic lethality with dpb11). Although the SLD7 gene is
not essential, cells deleting this gene (竏・ld7) showed sensitivity to hydroxyurea (inhibitor of
DNA replication) and MMS (DNA-damaging agent). Moreover, 竏・ld7 cells replicate
chromosomal DNA slower than wild-type cells. Furthermore, 竏・ld7 is synthetic lethal withtemperature-sensitive alleles of replication proteins, such as Sld3, Cdc45 and Sld2. These
results suggest that Sld7 plays an important role for DNA replication. To know function ofSld7, we tried to isolate factors interacting with Sld7 and found that Sld7 forms a complex
with Sld3. These proteins expressed in Escherichia coli actually formed a complex. In 竏・
ld7 cells, the protein level of Sld3 decreased and high copy SLD3 suppressed defect of 竏・
ld7 cells. Moreover, high copy SLD7 suppressed the growth defect of one of temperatureallele of SLD3. Thus, all the results suggest that Sld7 functions for DNA replication through
Sld3.

Epigenetic maintenance of the expression state of the genome appears to be crucial fordevelopment. Drosophila Trithorax-like (Trl) gene is a member of trithorax group andencodes the GAGA factor that binds to a GAGAG sequence on DNA. The GAGA factor
directs chromatin remodeling to its binding sites. We have shown that Drosophila FACT, aheterodimer of dSSRP1 and dSPT16, associates with the GAGA factor, binds to anucleosome, and facilitates GAGA factor-directed chromatin remodeling. Physical andfunctional interactions between the GAGA factor and FACT implicated the GAGA factorFACT complex in the modulation of chromatin structure for the maintenance of gene
expression (Nakayama et al. 2006).
Previous study from this laboratory has shown that the GAGA factor recruits the SWI/SNFtype chromatin remodeling factor PBAP complex to the regulatory regions of Hox.
Consisitent with this finding, we observed genetic interactions between Trl and polybromo
encoding a unique subunit of the PBAP complex.
Previously we found that the GAGA factor directs chromatin remodeling and replacement ofhistone H3 by its variant H3.3, and maintains white expression against the heterochromatin
spreading. In good agreement with this finding, we demonstrated that the GAGA factor
recruits HIRA, a specific chaperone for histone H3.3, to the white locus, and also found thata hira mutation enhances PEV (Nakayama et al. 2007).
RSF is a chromatin remodeting factor consisting of a regulatory subunit RSF1 and acatalytic subunit ISWI. We found that RSF1 contributes to Polycomb-dependent silencing in
addition to PEV.

Biochemical studies have shown that Spt6 is a transcriptional elongation factor. To
understand in vivo role of Spt6 in metazoans, we isolated mutants of Drosophila spt6
through imprecise excision of a P-element inserted in the coding region of spt6, and started
genetic studies on the factor.
Drosophila Ash1 encoding a SET domain protein is a member of trithorax group, but its
function remains unknown. We are trying to isolate a Drosophila Ash1 complex from atransgenic fly line expressing epitope-tagged Ash1.
Much of the genome is transcribed into long noncoding RNAs (ncRNAs). Previous datasuggested that bithoraxoid (bxd) ncRNAs of the Drosophila bithorax complex (BX-C)
prevent silencing of Ultrabithorax (Ubx) and recruit activating proteins of the trithorax group(trxG) to their maintenance elements (MEs). We found that, surprisingly, Ubx and several
bxd ncRNAs are expressed in nonoverlapping patterns in both embryos and imaginal discs,
suggesting that transcription of these ncRNAs is associated with repression, not activation,of Ubx. Our data rule out siRNA or miRNA-based mechanisms for repression by bxd
ncRNAs. Rather, ncRNA transcription itself, acting in cis, represses Ubx. The Trithorax
complex TAC1 binds the Ubx coding region in nuclei expressing Ubx, and the bxd region in
nuclei not expressing Ubx. We propose that TAC1 promotes the mosaic pattern of Ubx
expression by facilitating transcriptional elongation of bxd ncRNAs, which represses Ubx
transcription (Petruck et al., 2006).
(3) Role of DNA topology in the formation of active chromatin
Hirofumi Furuhashi, Kuniharu Matsumoto, Mikage Nakajima, Youhei Ogasawara andSusumu Hirose
Supercoiling factor (SCF) forms a complex with DNA topoisomerase II and generates
negative supercoils into DNA. Previous studies from this laboratory have indicated thatapproximately twice activation of the male X chromosome in Drosophila is achieved
through a balance between SCF forming an open and active chromatin and ISWI working
toward a compact and silent chromatin (Furuhashi et al., 2006). To elucidate themechanism underlying dosage compensation of the X chromosome, we started ChIP on
chip analyses to examine distribution of SCF along the male X chromosome.
Based on the preferential binding of psoralen to negatively supercoiled DNA, we havesucceeded in visualization of negatively supercoiled DNA domains within a cell. Using themethod, strong signals have been detected on heat shock puffs of Drosophila salivary
gland polytene chromosomes. The scs and scs’ sequences are required for detection of thestrong signals on the hsp70 genes upon heat shock. Consistent with this finding, genetic
studies revealed requirement of BEAF32 and ZW-5 proteins, that bind to scs and scs’, todetect the strong signals on hsp70.
(4) Functional cooperation between FACT and the MCM helicase complex
facilitates initiation of chromatin DNA replication
Bertrand Chin-Ming Tan1, Cheng-Ting Chien2, Susumu Hirose and Sheng-Chung Lee1,3(1Institute of Molecular Medecine, National Taiwan University, Taipei, Taiwawn; 2Institute of
Molecular Biology, and 3Institute of Biological Chemistry, Academia Sinica, Taipei, Taiwan)
Chromatin is suppressive in nature to cellular enzymes that metabolize DNA, mainly due tothe inherent inaccessibility of the DNA template. Despite extensive understanding of theinvolvement of chromatin-modifying factors in transcription, roles of related activities in DNA
replication remain largely elusive. Here we show that the heterodimeric transcriptional
elongation factor FACT is functionally linked to DNA synthesis. Its involvement in DNA
replication is partly mediated by the stable association with the replicative helicase

complex, MCM, and further by the coexistence with MCM on replication origin. Furthemore,relying on its nucleosome-reorganizing activity, FACT can facilitate chromatin unwinding by
the MCM complex, which is otherwise inert on the nucleosomal template. As aconsequence, the physical and functional interaction between FACT and MCM is an
important determinant in the normal initiation of DNA replication and conserved componentof the endogenous replication machinery, and support a model in which the concerted
action of helicase and chromatin-modifying activities promotes chromosome replication(Tan et al., 2006).
(5) The heterotrimeric G protein signaling organizes cell movements during
Drosophila gastrulation
Naoyuki Fuse, Takuma Kanesaki and Susumu Hirose
Gastrulation is a common developmental process and creates germ layers by dynamic
morphogenetic movements. In gastrulation of a Drosophila embryo, the ventral cells acquire
the mesodermal cell fate and undergo sequential cell movements. It has been shown thatthe concertina (cta) gene, encoding a Ga subunit of the heterotrimeric G proteins (Gproteins), is required for an initial event of the cell movements. However, mechanisms
underlying other cell movements and the G protein signaling in vivo are largely unknown. To
address these issues, we characterize the G protein signaling in the gastrulation process.
Since Cta and other Ga subunits are expressed ubiquitously at the gastrulation stage, we
examined mutants for these Ga subunits. Among them, the Gai mutant embryos showed
gastrulation defects, which are distinct from the phenotypes of the cta mutant, suggestingthat two Ga subunits regulate different cell movements.
Ric-8 has been thought to be an activator for the G protein signaling, however the role of
Ric-8 in vivo is still controversial. We identified a missense mutant for Ric-8, abortex, which
has been isolated as a female sterile mutant before. In the abortex mutant gastrulae, cell
movements were perturbed and the Cta signaling was compromised. These results suggestthat Ric-8 is involved in the turning of the G protein signaling to organize cell movements
during gastrulation.

In search of genetic changes responsible for human uniqueness, we are determining
genomic sequences of chimpanzee and gorilla that are phylogenetically close to human,and do molecular evolutionary analyses. In 2006, we have two publications on this subject.
(i) We compared nucleotide sequences of chimpanzee and human Y chromosomes anddescribed their evolutionary uniquness (Kuroki et al., 2006).
(ii) We examined human Endogenous Retrovirus (HERV)-R family in primates, anddescribed their hromosomal location, gene expression, and evolution (Kim et.al., 2006).
Molecular evolution of developmental regulation
Sumiyama Kenta, Kim Hyung-Cheol, Ishibashi Minaka, Saitou Naruya
We are studying cis-control elements of the developmental genes by sequence analysis andgene transfer experiments of large scale genomic clones, in order to elucidate relationshipbetween evolution of cis-elements and body plan.
Human population genetics
Saitou Naruya, Ishibashi Minaka
We are mainly interested in evolutionary relationship of various human populations. In 2006,
we hade two publications on this subject.
(i) ABCC12 was discovered to be earwax (cerumen) gene (Yoshiura et al., 2006).
(ii) We discussed relationship between genetic and linguistic differentiation of people inEurasia, in particular Japanese Archipelago (Saitou, 2006).
Evolution of blood group genes
Saitou Naruya
Blood group antigens are expressed on cell surface, and have a higher chance of being
affected by bacteria or virus. Therefore, their genes may have undergone positive selection.
We are studying evolution of ABO and Rh blood group genes for humans and non-humanprimates with collaboration of Dr. Kitano Takashi of Yamagata University School of
Medicine and Professor Antoine Blancher of Paul Sabatier University at Toulouse, France.
Genome scale evolutionary analysis
Saitou Naruya, Kawai Yosuke, Kim Hyung-Cheol, Masuyama Waka, Suzuki Rumiko,Takahashi Mahoo
We do genome-wide comparison of many protein coding and non-protein coding nucleotide
sequences among various organisms to elucidate evolutionary patterns. In 2006, weconducted systematic analysis of SNP data (mainly done by Kawai), ultra-conserved
elements (mainly done by Kim and Takahashi), protein domains (mainly done by
Masuyama), and synonymous susbstitution (mainly done by Suzuki).

RESEARCH ACTIVITIES(1) A novel long-range enhancer to specify the Sonic hedgehog (Shh) expression in the oralcavity morphogenesis
Tomoko Sagai, Takanori Amano, Yoichi Mizushina, Hiromi Yamamoto, Noriko SakuraiYamatani, Ayaka Okagaki, Masaru Tamura and Toshihiko Shiroishi
Shh is a secreted glycoprotein that is essential for the fundamental morphogenesis invertebrate embryogenesis. In developing embryos, Shh expresses in variousorganogenesis processes including head, lung, heart and limbs formation. Mutant mice inwhich normal Shh expression is affected in the organogenesis exhibit severe defects in therelevant organs. The Shh expression in a particular organogenesis is controlled by specificcis-acting regulatory elements. Recently, such several long-range enhancers have been
identified by cross species comparison of genome sequences and exploration ofconserved sequences among evolutionary remote species. A noncoding sequence,
MFCS1, localized in the 1Mb upstream of the Shh coding sequence is one of such cisacting elements, which includes limb bud-specific Shh enhancer (Sagai et al., 2005).
Here we report another novel long-range enhancer involving in morphogenesis of mouseoral cavity. MFCS4 is a phylogenetically conserved noncoding sequence residing in the
800kb upstream region of the Shh coding. In order to test whether the sequence acts as cisacting regulatory element, first we carried out transgenic assay with a LacZ-reporter geneflanked by the MFCS4 fragment. In the transgenic mice, we found that MFCS4 induces
expression of the reporter gene specifically in the oral epithelium of palate, epiglottis andarytenoid. Next, we conducted ES targeting to generate MFCS4 knockout (KO) mice. The
mice heterozygous for the MFCS4 KO did not show any defect. By contrast, the KO
homozygotes caused hypoplastic defects in the palate and epiglottis surrounding the nasopharyngeal opening. Because of this defect, airway of the homozygotes was disturbed, andeventually it resulted in neonatal lethality.
In the oral cavity of wild-type embryos, endogenous Shh expression was detected in palatal
and tongue epithelium and partially overlapped the expression domain of the reporter genein the transgenic mice. Then, we examined the Shh expression in the MFCS4 KO
homozygotes. Section in situ hybridization with a Shh riboprobe showed that in the MFCS4
KO homozygotes, Shh did not express in the oral epithelium where the signal of transgenic
reporter gene was detected. Finally, in order to confirm that MFCS4 is a cis-acting element,
we carried out a test cross of the Shh-coding KO and the MFCS4 KO mice. From the above
cross, we generated compound heterozygotes of the both KO alleles. We observed that allcompound heterozygotes exhibited the phenotype almost identical to that of the single
MFCS4 KO homozygotes. Thus, all data demonstrated that MFCS4 is a cis-acting element
including glossopharyngeal specific long-range enhancer of Shh.

(2) Chromatin dynamism of a long-range cis-regulator for limb bud-specific Shh expression
Takanori Amano, Tomoko Sagai, Hideyuki Tanabe1 and Toshihiko Shiroishi(1The Graduate University for Advanced Studies)
MFCS1 (mammal-fish conserved sequence) is located at the intron 5 of Lmbr1 locus, whichis 1 Mb apart from the Shh coding sequence. We have reported that elimination of MFCS1
causes a defect of Shh expression and distal truncation of skeletal elements of mouse limb.
It is suggested that MFCS1 is a limb bud-specific cis-acting regulatory element of Shh(Sagai et al., 2005). This fact raises a question of how MFCS1 controls a transcription of
Shh beyond such a long distance. To address this question, we paid attention on higherorder chromosomal structure surrounding the Shh locus.
To examine topological relationship of the Shh coding region and MFCS1, we performed
3D-FISH analysis using fluorescent-labeled probes that hybridize with these two genomic
regions. We dissected anterior, intermediate and posterior portions of developing limb
buds at E10.5 embryos. The posterior portion of limb bud is referred to as zone ofpolarizing activity (ZPA) and it expresses Shh exclusively in wild-type mice. We immediately
prepared single cell suspension from the each dissected specimen, and used for the FISH
analysis. After capturing 3D images of the two fluorescent signals, physical distance
between the Shh coding region and MFCS1 was computationally calculated. This resultclearly indicated that the mean distance in the posterior limb bud cells was significantly
shorter than that in the intermediate limb bud cells, suggesting that MFCS1 tends toapproach the Shh locus in the Shh-expressing cells. Notably, the mean Shh-MFCS1
distance in the anterior limb bud cells was somewhat smaller than that in the posterior limb
bud cells, but the value was close to that in the posterior limb bud cells. It is known that many
mouse mutants exhibit ectopic Shh expression at the anterior margin of limb buds, and it
lead to preaxial polydactyly. It is, therefore, conceivable that the anterior limb bud cellpotentially has a competence to express Shh. Thus, adjoining of physically distant two
regions, MFCS1 and the Shh coding, implies that the cells have a competence forexpressing Shh.
To further investigate the chromatin dynamism surrounding the Shh coding and MFCS1
regions, we adopted a method of chromosome conformation capture (3C). Limb buds fromE10.5 embryos, which express Shh at very high level, were used for the analysis. We used
limb buds from E12.5 embryo, in which Shh expression already ceased, as a control. As aresult, we captured an expected positive signal only in the limb buds from E10.5 embryos,
suggesting that MFCS1 physically interacts with the Shh coding region in Shh-expressing
cells.
(3) Molecular mechanisms of epithelium formation of skin and gastrointestinal tract in mice
Masaru Tamura, Shigekazu Tanaka, Tomoaki Fujii, Hiromitsu Komiyama1 and Toshihiko
Shiroishi(1Graduate School of Medicine, Juntendo University)
Epithelial cells are tightly connected to one another in sheets and tubes, and form epidermis
and mucosal epithelium of gastrointestinal tracts. Homeostasis of the epithelial linings iscontrolled by the balance between proliferation of the stem cells and apoptosis following
terminal differentiation. Disruption of this balance may cause abnormal cell proliferation andseveral diseases like as cancers. However, our knowledge on the molecular basis
underlying the epidermis development and homeostasis is still limited. We have overcome
this problem using the forward and reverse genetics approaches. We performed threefundamental studies: (i) Screening and phenotype analysis of mutant mice, which exhibit
abnormal epidermal development; (ii) identification of causative gene of these mutant mice;(iii) analysis of these gene functions using the transgenic and gene knockout technique. We
identify five novel genes during the analysis of just one mutant mouse. Four of five thesegenes are clustering in the mouse chromosome 15, and these genes have several

conserved sequences and novel functional motifs. Each of these genes is expressed in theepidermis and gastrointestinal tract (GI) in a tissue specific manner, and expression
patterns and levels were depended heavily on proximal-distal axis in the GI tract. We arenow examining the function of these genes using the reverse genetics approach.
(4) Transgenesis with a modified-BAC DNA harboring the Rim3-type GsdmA3 mutation
recaptures the mutant skin phenotype
Shigekazu Tanaka, Masaru Tamura, Aya Aoki1, Tomoaki Fujii, Hiromitu Komiyama2,
Toshihiko Shiroishi(1Department of Neurosurgery, Tokyo Metropolitan Hiroo Hospital 2Graduate School of
Medicine, Juntendo University)
In our previous study, we showed that a spontaneous dominant skin mutant, Rim3, has apoint mutation in Gasdermin A3 (GsdmA3). The Rim3 mutation has a single basesubstitution, 1124 G to A, which results in a missense change, alanine 348 threonine. To
confirm that the genetic alteration found in the GsdmA3 gene causes the mutant phenotype,in this study we carried out transgenesis using a modified-BAC DNA containing the Rim3type GsdmA3 mutation (alanine 348 threonine). A BAC clone RP23-438D7 contains 160 kb
genomic region that includes GsdmA cluster except for GsdmA1 and most likely contains
the promoter and the cis-regulatory elements of GsdmA3 gene within its 115 kb upstream
fragment of GsdmA3. We introduced the Rim3-type mutation into the exon 9 of GsdmA3 inthe RP23-438D7 clone by means of BAC modification technology. The modified BAC
construct was transferred into genome of wild-type (DBA/2J x C57BL/6J)F1 mice. We
selected transgenic mice by genotyping for the vector sequence, and established threetransgenic founder lines carrying the Rim3-type GsdmA3 mutation. We found that these all
three lines exhibit skin phenotype similar to that of Rim3. Histological analysis revealed thatthe transgenic mice have degenerated hair follicles at 10 months of age as was observed in
Rim3 mutant mice. In contrast, transgenic mice that express wild-type GsdmA3 did notexhibited any phenotype in the skin. The result clearly demonstrated that GsdmA3 is thecausative gene for Rim3.
(5) Disruption of genetic interaction between two autosomal regions and the X chromosome
causes hybrid breakdown in a mouse intersubspecific cross

Moriwaki3 and Toshihiko Shiroishi(1The YS Institute, Inc., 2Hokusei Gakuen University, 3RIKEN BioResource Center)
Reproductive isolation that initiates speciation is likely caused by incompatibility between
multiple loci in organisms belonging to genetically diverging populations. Laboratory
C57BL/6J mice, which predominantly originated from Mus musculus domesticus, and a
MSM/Ms strain derived from Japanese wild mice (M. m. molossinus) are reproductively
isolated. These two strains exhibit hybrid breakdown: F1 hybrids are fertile, but succeeding
intercrosses result in male sterility. A consomic strain, C57BL/6J-ChrXMSM, which carries
the X chromosome of MSM/Ms in the C57BL/6J background, shows male sterility,
suggesting genetic incompatibility of the MSM/Ms X chromosome and other C57BL/6J
chromosome(s). In this study, genome-wide linkage analysis and subsequent QTL mapping
successfully detected significant QTLs on chromosomes 1 and 11 that interact with the X
chromosome and are responsible for the hybrid breakdown. This was confirmed by theobservation that introduction of the MSM/Ms chromosomes 1 and 11 into the C57BL/6JChrXMSM background partially restored fertility. Thus, genetic interactions between the two
autosomal regions and the X chromosome have a crucial role in proper spermdifferentiation, and their disruption causes hybrid breakdown. Intracytoplasmic sperm
injection and zona-free in vitro fertilization showed that the C57BL/6J-ChrXMSM
spermatozoa have a defect in penetration of the extracellular zona pellucida. Moreover, two-dimensional electrophoretic proteome study of whole proteins from sperms provided
considerable candidates responsible for the sterility of C57BL/6J-ChrXMSM males.
(6) QTL analysis of hereditary predisposition of obesity based on inter-subspecific cross of
C57BL/6J and MSM/Ms strains
Akiteru Maeno, Hideko Watanabe, Akihiko Mita, Ayako Oka and Toshihiko Shiroishi
Obesity is a highly heritable and genetically complex trait with hundreds of potential lociidentified. In order to elucidate the genetic determinants of this disease, we are taking
approach to use mouse models for heritable obesity. In this study, we conducted genetic
analysis of obesity-related quantitative traits based on the cross between a standard
laboratory mouse strain C57BL/6J (B6) and a Japanese wild mouse-derived strain
MSM/Ms (MSM). The quantitative traits that we analyzed in this study are followings: bodyweight, body weight that excludes total fat pat weight (lean body weight), percentage of fat
pat surrounding each of three visceral tissues (gonad, retroperitoneum and mesenterium) tolean body weight, percentage of sum of the above three visceral fad pat weight to lean bodyweight, percentage of subcutaneous fad pat weight to lean body weight and total fat pat
weight to lean body weight (adiposity index: A.I.).
MSM has higher A.I. value than that of B6 at ten weeks of age, and this tendency became
more prominent as age proceeded. This suggests that MSM shows higher predisposition toobesity as compared with B6. For the quantitative trait loci (QTL) analysis, we crossed B6
and MSM mice and generated F1 hybirds, and subsequently intercrossed the F1 mice andobtained totally 272 F2 progeny. Then, we carried out QTL analysis to identify lociresponsible for eight obesity-related traits described above. First, single-locus genome
scans analysis identified four QTLs on Chr 2, 6, 9 and 13, all of which control A.I. value. All
these QTLs showed sex-dependent effect. For the three QTLs on Chr 6, 9 and 13, MSM
alleles increase A.I. value, while B6 allele increases the A.I. value for the QTL on Chr 2.
Because all four QTLs explain relatively small proportion of the variance observed in the F2progeny (only 9 to 11% of the total variance), many other minor QTLs and epistaticinteraction of two independent loci were expected to be contributed to the genetic variance.
Therefore, we implemented pairwise genome scan analysis for the same data set of the
272 F2 progeny. As a result, we identified a significant epistatic interaction between twoloci on Chr 9 and 13.
QTL analyses with Multiple Interval Mapping (MIM) and Bayesian Interval Mapping (BIM) arethought to be more suitable for the cases in which multiple QTLs are responsible complex
traits. We need further studies using the above analyses to reveal hidden QTLs that were
not detected in this study.
(7) Genetic dissection of obesity using mouse consomic strains
Toyoyuki Takada, Akiteru Maeno and Toshihiko Shiroishi
Obesity is a common disease and a major risk to develop type 2 diabetes mellitus andmetabolic syndrome. Genetic obesity is generally thought to be multifactorial disease, whichis caused by multiple genetic determinants and influence of environmental factors. To
understand pathology of obesity, genetic analysis of responsible genes for this complex trait
has been prominent issue as in many common human diseases. We are taking approach touse mouse models for obesity. C57BL/6J-ChrMSM consomic strains were constructed bytransferring individual chromosomes from MSM/Ms strain, derived from Japanese wild
mouse, Mus musuculs molossinus, into the genetic background of a standard laboratory
strain C57BL/6J, which was derived from west European wild mouse, M. m. domesticus.
These consomic strains are strikingly useful for chromosome mapping of various
phenotypes, because above two mouse strains showed extremely large extent ofphenotypic variations based on vast amount of genomic differences (~ 1% SNP). Our
preliminary phenotyping of the consomic strains indicated a variety of range in susceptibilityor resistance to obesity or obesity-related phenotypes among the strains. Based upon thestrain difference, we intend to explore genes and genetic pathways underlying the polygenic
obesity. At the first step, now we are conducting more detailed characterization of thephenotype of each consomic strain using following tests: 1) measurement of consumption offoods (normal chaw and high fat diet, etc.) and body weight, 2) detection of metabolismrelated parameters (activity, body fat content, blood and hepatic lipid content, plasma insulin
and leptin levels, etc), 3) radiographical measurement of adipose tissue mass using
computer tomography (CT) scanning, 4) transcriptome analysis of metabolism-related
tissue of all consomic strains.

RESEARCH ACTIBITIES(1) Molecular mechanism of somite segmentation
Mitsuru MORIMOTO, Nobuo SASAKI, Makoto KISO and Yumiko SAGA
We have been investigating the in vivo function of the bHLH transcription factor, Mesp2, forwhich the periodic expression of both mRNA and protein appears in the anterior PSM.
Mesp2 plays key roles in the anterior PSM, at the point of transition of the paraxial
mesodermal cells from the PSM to somites. In addition, we have previously shown that
Mesp1 is a closely related member of the Mesp-family of genes, which share significant
sequence homology in their bHLH regions. We have attempted to define the functional
domains of the Mesp2 protein by focusing on the vertebral development reflecting rostrocaudal properties of somites in vivo. We find that Mesp2 contains a degradation domain,which acts as a target of proteasome-mediated proteolysis and appears to play this role invivo. We have also defined the nuclear localization signals (NLS) and constructed aminimum Mesp2 protein (P2-HD) composed of the NLS, bHLH and the degradation
domains. The ability of the P2-HD as a transcription factor in vivo was examined. Some ofthe defects that had been previously observed in the Mesp2-null mice were rescued in theknock-in mice but only in the posterior half of the body, indicating differential effects of P2HD along the anterior-posterior (AP) axis. In addition, quantitative analysis of the expression
along the AP-axis revealed that the relative levels of Mesp2 increased, whereas Mesp1 isdown-regulated in the later stages of development by the activities of Mesp2 in the wild-type
embryo. Moreover, we have found that somitogenesis in the early stages is more
susceptible to changes in the Mesp gene dosage, indicating that a threshold level of Mesp
activity must be required for the progression of normal somitogenesis.
(2) Regulation of Mesp2 gene expression
Mitsuru Morimoto, Masayuki OGINUMA, Nobuo Sasaki and Yumiko SAGA
The transcription factor, Mesp2 plays essential roles in the segmental border formation andestablishing rostral-caudal patterning within somites. A possible Mesp2 target gene,
Ripply2 is identified by microarray analysis as one of genes down-regulated in the Mesp2null mouse. Ripply2 encodes a possible transcriptional co-repressor containing WRPW
motif. We find that Mesp2 could bind to the enhancer of Ripply2 gene, indicating that
Ripply2 is a direct target of Mesp2. We asked whether the Ripply2 is responsible for the
repression of genes under the control of Mesp2 by generating the Ripply2 knockout mouse.
Unexpectedly, Ripply2-null embryo showed rostralized phenotype that is contrastive to thatof Mesp2-null mice. Gene expression studies together with genetic analyses revealed that
Ripply2 turned out to be a negative regulator of Mesp2. The lack of Ripply2 results in theprolonged expression of Mesp2, which leads to the rostralized phenotype via suppressing
Notch signaling. The Mesp2/ Ripply2 double-null mutant shows almost similar phenotype tothat of Mesp2-null mutant, confirming that Ripply2 functions exclusively thoroughsuppression of Mesp2.
(3) Functional analyses of Hesr1 and Hesr2 in the cardiovascular development
Hiroki KOKUBO, Raul VizcardoSakoda, and Yumiko SAGAThe establishment of chamber specificity is an essential requirement for cardiac
morphogenesis and function. Hesr1 and Hesr2 are specifically expressed in the atrium andventricle, respectively, implicating these genes in chamber specification. In our current
study, we show that the forced expression of Hesr1 or Hesr2 in the entire cardiac lineage
results in the reduction or loss of the atrioventricular (AV) canal. In the Hesr1-misexpressed
heart, the boundaries of the AV canal have a poorly defined appearance, and theexpression levels of specific markers of the AV myocardium, Bmp2 and Tbx2, areweakened or undetectable. More potent effects could be observed in Hesr2-misexpressed
embryos, in which the AV canal appears to be absent entirely. These data suggest that
Hesr1 and Hesr2 may prevent cells from expressing the AV canal specific genes that leadto the precise formation of the AV boundary. Our current findings further indicate thepossibility that Tbx2 expression is directly suppressed by Hesr1 and Hesr2. Furthermore,
we find that the expression of Hesr1 and Hesr2 is independent of Notch2 signaling. Taken
together, our data thus demonstrate that Hesr1 and Hesr2 play crucial roles in AV boundary
formation through a Notch independent pathway.
(4) Functional redundancy between Nanso2 and Nanos3
Atushi SUZUKI and Yumiko SAGA
The mouse Nanos proteins, Nanos2 and Nanos3, are required for germ cell development
and share a highly conserved zinc finger domain. The expression patterns of these factors
during development, however, differ from each other. Nanos3 expression in the mouseembryo commences in the primordial germ cells (PGCs) just after their formation and a lossof this protein results in the germ cell-less phenotype in both sexes. In contrast, Nanos2
expression begins only in male PGCs after their entry into the genital ridge and a loss of thisprotein results in a male germ cell deficiency, irrespective of the co-expression of Nanos3 inthe these cells. These results indicate that these two Nanos proteins have distinct functions,depending on the time and place of their expression. To further elucidate this, we havegenerated transgenic mouse lines that express Nanos2 under the control of the Oct4ΔPE
promoter and examined Nanos2 function in a Nanos3-null genetic background. We find that
ectopically produced Nanos2 protein rescues the Nanos3-null defects as the germ cells fully
develop in both sexes in the transgenic mice. This result indicates that Nanos2 cansubstitute for Nanos3 during early PGC development. In contrast, our current data show that
Nanos3 does not rescue the defects in Nanos2-null mice. Our findings thus indicate that
there are redundant functions of the Nanos proteins in early PGC development but that
Nanos2 has a distinct function during male gem cell development in the mouse.
(5) Functional analysis of nanos3
Hitomi SUZUKI, Makoto KISO and Yumiko SAGAIn the Nanos3-null mice, the number of PGCs rapidly decreased during their migration,
indicating that Nanos3 is responsible for the maintenance of PGCs rather than theirgeneration. There are two possibilities for the loss of PGCs, apoptotic cell death orabnormal differentiation to somatic cells. By the immunostaining, we detected apoptosis in
migrating PGCs in Nanos3-/-mice. In addition, we have generated the Nanos3-cre mouse inwhich the cre recombinase gene is knocked in the endogenous Nanos3 locus. By crossing
with the Rosa26 reporter mouse, we are able to visualize Nanos3 expressing PGC cells by
・｢-gal staining. In the presence of Nanos3, ・｢-gal positive cells were incorporated into thegenital ridge, indicating that these cells were PGCs. In addition, we observed ・｢-galpositive cells in the tail bud. These cells were lost during development since they failed toenter PGC program. In the absence of Nanos3, although some cells in the tail bud showed ・｢-gal activity, we could not observe any ・｢-gal positive cells in the genital ridge. Importantly

we did not observe expansion of ・｢-gal positive somatic cells in any other cell lineages,
which strongly indicates that Nanos3 is required for maintaining PGCs by preventing
apoptosis and the lack of Nanos3 does not result in the cell fate change into the somatic
cells.

RESEARCH ACTIVITIES(1) Single-molecule dynamics of translation termination.
Hideki NAKAYAMA, Kouichi ITO, and Nobuo SHIMAMOTO
Single-molecule analysis has not been much applied to translation, although it can provide
critical conclusions to several important problems such as order of association/dissociationof components. Therefore, we are challenging to solve a long-standing problem intermination: whether mRNA dissociates from 70S or from 30S subparticle. If it dissociatesfrom 70S, genes on the same mRNA can be translated in cis by sliding of 70S, but if not,the whole initiation process has to be repeated. Furthermore, the growth-phase control ofconversion from 70S into 100S inactive particles should have different pathways dependingon the termination mechanism.
At first, we have developed a surface treatment of glass sides that has NTA residues but
does not adsorb nonspecific substance in an extract prepared from E. coli. Next, we
tethered ribosome at its 30S through the binding between NTA and his tag introduced in an
Rps protein. The 50S of this ribosome has an Rpl protein fused with GFP and thus thelocations of ribosome molecules were identified by its fluorescence. The tethering ofindividual ribosome molecules was shown by a single-step photo bleaching of the GFP. We
prepared an mRNA encoding Lumio-his-tag, and the RNA is labeled with ca. 10 Texas Red
moieties at its 5’-end. The translational product was fixed on the NTA surface and detectedby Lumio Green, proving the activity of the tethered ribosome molecules. The movements of
GFP and Texas Red spots should yield the conclusion. A preliminary experiment showed
the presence of dissociation of mRNA from 70S, and now the fraction of that from 30S areunder examination.
(2) Construction of DNA library by PCR with a single primer.
Hideki NAKAYAMA, Ryusuke FUJITA and Nobuo SHIMAMOTO
For studies of bacterial infection and cloning from an environment, there are cases where
only an amount of DNA as small as direct PCR is available to target DNA segments inconstructing a DNA library. PCR with primers of random sequences are used in such acase but is often unsatisfactory because of poor and/or biased amplification. We havedeveloped a complementary method of PCR to use a single primer. This method wassuccessful for 0.1-1 ng of E. coli DNA and examination at 30 loci showed less than 100-folddifferences in amplification. The core heart of this method is the selection of the primer. We
screened the best 10 base primer and found that the 6 base at 3’-end must reflect the mostfrequent hexamer sequences in the genome, while the 4 base at 5’-end does not affect theamplification in our PCR condition. The drawback of this efficient construction of library is
the formation of recombinants of two or more loci during the amplification. However, this is

(3) Genetic and biophysical study on σ70 of E. coli RNA polymerase.
Suganthan Rajan Babu, Akiko Hatakeyama, and Nobuo Shimamoto
σ70 is a subunit of E. coli RNA polymerase and mainly interact with a promoter. Its fusion
with GFP tends to be cleaved in cells and thus GFP must be inserted in σ70. One of suchmutant σ70 showed a distinct cleavage at the middle of Region 2.4 of σ70, leaving the Nterminus fragment containing GFP and Regions from 1.1 to 2.3. The C-terminus fragment
was not significantly accumulated in the cell. We quantitative analyses of the activity of thepurified enzyme and the fraction of the cleavage fragment, there is possibility that the Nterminus fragment is bound to core RNA polymerase. We are analyzing the activity of the
enzyme harboring the N-terminus fragment.
We have found that an E. coli strain with rpoD(the gene encoding σ70) can grow 2°C higher
temperature than the wild type, when it harbor on a plasmid a chimeric rpoD with its Region
4.2 is replaced that of sigA of T. thermophilus. To clarify the relationship with ropD andupper limit of the growing temperature of an E. coli strain, we have constructing mutants ofrpoD.
(4) Immobilization of protein and nucleic acid on diamond needle.
Yosuke Amemiya and Nobuo Shimamoto
To inject a substance in a cell, glass capillaries are conventionally used and its technology
has been matured to show clear limitations on the size of cells and the size of needles. Only
large eukaryotic cells like oosites are available to the technique and the cells cannot standfor multiple injections. The finer the needles, the better the viability of cells after injection.
Therefore, finer needles are expected to give better results but the material is limited
because of the stiffness. Diamond is the hardest material and biologically inactive, and thus
expected to a new material for finer needles to carry a substance in or take a biologicalmaterials out of the cells. Therefore, it is essential to develop a good surface of diamondthat can immobilize various biological molecules. We are challenging to make such surface
in collaboration with the Diamond Group of AIST and a Group of Olympus.

RESEARCH ACTIVITIES(1) Enhancement of chemotaxis by pre-exposure to odorants and food in thenematode C. elegans
Ichiro TORAYAMA, Hiroshi ICHIJO, Kotaro KIMURA, Takeshi ISHIHARA1 and Isao
KATSURA (1Kyushu University)
We have found that C. elegans specifically enhances chemotaxis to butanone, but not tobenzaldehyde, by pre-exposure to butanone and food. This odor-specific plasticity, which
we call butanone enhancement, is different from the already known inhibition of olfactory
adaptation by food. In the latter case, the chemotaxis index never exceeds that of naive
animals, and food can be replaced by serotonin, which is not true for butanone
enhancement. To elucidate the molecular mechanism, we isolated ten mutants that showedabnormality in this plasticity. Of these mutants, olrn-1(ut305) and olrn-2(ut306) were studied
in detail. The olrn-1 gene encoded a novel protein containing predicted transmembrane
domains and acted in AWC olfactory neurons for butanone enhancement and for the AWC
neuronal asymmetry. Namely, while the wild-type animal is known to express str-2 gene in
only one of the two AWC neurons, the olrn-1(ut305) mutant expressed str-2 in neither ofthem. We then hypothesized that the absence of the str-2-expressing AWC neuron (AWCON
neuron) is the reason for the defect in butanone adaptation, and proved it by various
experiments, including the butanone enhancement assay of AWCON-killed wild typeanimals. We also cloned the olrn-2 gene and found that it was allelic to bbs-8, one of theBardet-Biedl syndrome (bbs) genes. The olrn-2(ut306) mutant showed the wild-type
phenotype in the AWC asymmetry, and the olrn-2 gene was required in the AWCON neuron
for butanone enhancement. The olrn-2(ut306) mutant showed structural defects in sensory
cilia like known bbs mutants. We therefore tested many cilium structure mutants forbutanone enhancement. The results revealed that all the Bardet-Biedl syndrome mutantstested were abnormal, while other cilium structure mutants were normal in butanone
enhancement. Besides butanone enhancement, we found similar plasticity with isoamyl
alcohol.
In 2006, we found that pre-exposure to butanone and the odor of food enhances chemotaxis
to butanone. This result shows that AWC neurons are strong candidates of neurons thatsense food for butanone enhancement, because butanone enhancement was not impairedby mutations that block the sensation of other known olfactory neurons (lim-4 for AWB andosm-9 for AWA, ASH, and ADL). We also found behavioral plasticity similar to butanone

enhancement with 2,3-pentanedione. We are now investigating the relationship between
this plasticity and the plasticity with butanone and isoamyl alcohol.
(2) Genetic analysis of the plasticity of avoidance behaviors in C. elegans
Kotaro KIMURA and Isao KATSURA
We have recently discovered a novel type of plasticity in the avoidance response of C.
elegans: The avoidance response of the animal to repellent odors was enhanced, rather
than being reduced, after preceded exposure to the odor. It was somewhat surprisingbecause almost all of the previously known stimuli (including other repellent stimuli) to theanimals cause adaptation, i.e., the reduction of the sensory response after preceded
exposure. In general, adaptation has been extensively studied in various sensory systems.
However, the enhancement of the sensory response has been far less studied, particularly
at the molecular level, with an exception of mammalian pain sensation and gill-withdrawal
reflex in Aplysia. Therefore, analyzing the enhancement of the avoidance response of C.
elegans may lead to the identification of a novel regulatory mechanism of the sensory
response enhancement in general.
To gain insight into the molecular mechanism of the enhancement of 2-nonanone avoidance
behavior, we have carried out a candidate screening and found that several mutants
showed specific defects in the enhancement of avoidance behavior. We are currently
analyzing the details of the phenotypes of the mutants.
In addition, we are developing a quantitative analysis system for the animals' movement.
Preliminary results suggest that there are differences in the direction and in the speed
between the avoidance behaviors to 2-nonanone and 1-octanol, two repulsive odors mainly
sensed by different types of sensory neurons, AWB and ADL, respectively.
(3) Class 1 flr mutants of the nematode Caenorhabditis elegans
Yuri KOBAYASHI, Kotaro KIMURA and Isao KATSURAClass 1 flr mutants of C. elegans, which map in flr-1, flr-3 and flr-4, were isolated originallyby resistance to 0.4 mg/ml NaF (Katsura, I. et al.: Genetics 136, 145-154, 1994). They also
showed many other phenotypes including slow growth, short defecation cycle periods (Decs), frequent skip of the expulsion step of defecation, synthetic abnormality in dauer larva
formation, weak tendency to stay on food, and hypersensitivity to serotonin. The flr-1 geneencoded a cation channel of the DEG/ENaC superfamily, while flr-4 and flr-3 coded for anovel Ser/Thr protein kinase and a kinase-like molecule, respectively, both having ahydrophobic domain at the carboxyl terminus. They were expressed essentially in theintestinal cells, except that flr-4 was expressed also in the isthmus of the pharynx and in apair of head neurons called AUA. We consider that class 1 flr genes constitute a regulatory
system that acts in differentiated intestinal cells.
In 2006 we continued the following experiments. To reveal the mechanism of the regulationof defecation cycle periods, we looked for genes, the RNAi of which suppress the Dec-s
phenotype of the flr-1(ut11) mutant or the Dec-l phenotype of animals expressing the FLR-1
ion channel lacking the C-terminal cytoplasmic domain (FLR-1ΔC). We also investigated
the role of the C-terminal cytoplasmic domain by making various deletion mutants in thisregion. The C-terminal domain is exceptionally large for an ion channel of the DEG/ENaC
family and contains many putative phosphorylation sites.
(4) Class 2 flr mutants of the nematode Caenorhabditis elegans

Akane OISHI, Kotaro KIMURA, Takeshi ISHIHARA1 and Isao KATSURA (1Kyushu
University)
Class 2 flr mutations were isolated first as a weak fluoride-resistant mutation and then as
suppressors of the slow growth or serotonin-hypersensitivity of class 1 flr mutations.
Besides these phenotypes, they also suppressed the dauer larva formation abnormality andweak tendency to stay on food, but not the defecation abnormalities or strong fluorideresistance. The phenotypes suggest two possibilities on the relationship between class 1
and class 2 flr genes. (a) Class 2 flr genes may act downstream of the class 1 regulatory
pathway. At the downstream, the regulatory pathway may bifurcate into two branches, thegrowth/dauer/chemosensory branch and the defecation/fluoride sensitivity branch, whileclass 2 genes act in the former branch and not the latter. (b) Class 2 flr genes may act
antagonistically to class 1 genes, while the threshold is different for thegrowth/dauer/chemosensory phenotypes and the defecation/fluoride sensitivity phenotypes.
Class 2 mutations mapped in four genes, flr-2, flr-5, flr-6 and flr-7, of which only flr-2 hasbeen cloned. flr-2 encoded a secretory protein belonging to the gremlin/DAN/cerberus
family. A functional flr-2::GFP fusion gene was expressed in some neurons in the head andthe tail as well as many pharyngeal neurons. We found that FLR-2 interacts in vitro with asecretory protein encoded by the ZK20.1 gene and isolated a deletion mutant in this gene.
A ZK20.1::GFP fusion gene was expressed in the intestine and body wall muscles.
In 2006, we continued the study on the role of ZK20.1 in defecation cycle length regulation.
Both the deletion mutation and RNAi of ZK20.1 did not change defecation cycle length ofwild type animals, but they increased that of flr-2;flr-4 double mutants and a weak flr-4
mutant (n2259). We are also trying to clone flr-6 and flr-7 despite the technical difficulty of
the rescue experiments.
(5) Analysis of synthetic
Caenorhabditis elegans

dauer-constitutive

mutants

inthenematode

Norio SUZUKI1, Takeshi ISHIHARA2 and Isao KATSURA (1Riken CDB, 2Kyushu University)
If newly hatched larvae of C. elegans are in a crowded state and given a limited foodsupply, they sense the environmental signal of pheromone and food with a head sensory
organ called amphid, and deviate from the normal life cycle, ending in non-feeding larvae
called dauer larvae. We are investigating synthetic dauer-constitutive (synDaf) mutants, i.e.,mutants that form dauer larva in a certain mutant background even in the presence of plenty
food and at low population density. We found that mutations in more than 50 known neuralgenes show synDaf phenotypes. We are studying the combinations of mutations for the
synDaf phenotype and the pattern of suppression of the synDaf phenotype by various
suppressor mutations. In this way we hope to elucidate the detailed regulatory pathway fordauer larva formation.
Furthermore, to identify new genes for the regulation of dauer larva formation, we haveisolated and mapped 44 mutations that show the synDaf phenotype in the unc-31(e169)background, where unc-31 gene encodes CAPS protein, which is thought to act in thesecretion of biogenic amines and peptides. These mutations mapped at least to 17 genes,of which sdf-9, sdf-13, and sdf-14 have been cloned. sdf-9 encoded a protein tyrosine
phosphatase-like molecule, was expressed in a pair of neuron-associated cells called
XXXL/R, and regulated dauer larva formation in the steroid hormone signaling pathway. sdf13 encoded a homologue of the transcription factors Tbx2 andTbx3 and controlled olfactory
adaptation in AWC and dauer larva formation in cells other than AWC (possibly ASJ)
neurons. sdf-14 was allelic to mrp-1, a homolog of the MRP1 (multidrug resistanceassociated protein 1) gene, which acted in neurons, pharyngeal muscles and intestinal cells
for dauer regulation. Interestingly, human MRP1 could substitute for C. elegans MRP-1 indauer larva regulation, and an inhibitor of the human MRP1 export activity impaired thisfunction, showing that the export activity is required for normal dauer larva regulation.
In 2006, we examined a huge amount of data on the synDaf phenotypes of known mutations
to find rules. We plan to write a paper using these data and those on the mapping and initialcharacterization of the mutants we isolated.

RESEARCH ACTIVITIESWide scale gene family analysis under the point of view of expression.
Andrea Cornero, Margherita Squillario, Kazuho Ikeo and Takashi Gojobori.
In order to discover new details about how the mechanism of transciption works, a widescale analysis of heterogeneous data regarding gene families in both human and mousehas been performed. Studying different kinds of data (such as expression data, sequences
data, transcription starting site distributions, etc.), can reveal important relationship between
the characteristic of the genes and of their promoters. These relationships can then give us
some new information about the complex regulation of the transcriptional process.
Preliminary result showed that genes with similar distribution and number of transcription
starting site have also a similar profile of expression. Further analysis revealed that there's
no apparent relationship between the similarity of the aminoacidic sequence of the genes
and the similarity of their expression profiles. From this preliminary result, it is possible toassume that the evolutionary process of the promoter and the coding regions is
independent.
The sensory apparatus of hydra.
Hwang Jung Shan, Yasuharu Takaku, Kazuho Ikeo and Takashi Gojobori
Nematocyte is the stinging cell present in all cnidarians. They are specialized for the prey
capture, the defense and the attachment on substances. Nematocyte can be triggered andreleases its ‘explosive’ nematocyst that subsequently kills its preys. Early investigations
indicated that ciliary structures on the apical surface of nematocyte react to the mechanicalstimuli and it was later named cnidocil apparatus. To understand the molecular structures ofcnidocil apparatus and its evolutionary perspective, we collected genes with expressions at
the late differentiation of nematocyte (the stage when cnidocil apparatus is assembled). As
a result, we identified four genes expressed at the late differentiation by whole mount in situ
hybridization. We also performed immuno-fluorescent method with antibodies raised
against these gene products. Two proteins are structurally crucial for the formation of
cnidocil apparatus and they both contain intermediate filament domains. The other two arecytoplasmic proteins which interact with calcium ions. Homologues of these calcium-binding
proteins were found to express in the vertebrate inner ear hair cell and play a role incalcium-dependent signal transduction. This leads us to the conclusion that cnidarians andvertebrates might share a common origin of mechanosensory apparatus and likely bothmechanosensory systems play similar roles in response to external stimuli.
The Evolutionary Origin of Mammalian Neocortex
Ikuo Suzuki, Tatsumi Hirata, and Takashi Gojobori
Neocortex of the mammalian brain is known to control highly integrated functions such as
logical consideration and speech of a language. Because only mammals including humans

have a laminated structure of the neocortex, this well-organized structure may be needed forconstructing the neural circuits by which enormously complex information can be precisely
processed. However, the molecular backgrounds of how mammalian laminated neocortex
evolved have been totally unknown. With the aim of elucidating the evolutionary origin andprocess of the mammalian laminated neocortex at the molecular level, I conducted acomparative study of developmental processes between the mammalian neocortex and thenon-mammalian corresponding region, the pallium. In the present study, I took a chickpallium as a non-mammalian model, because the chick brain is relatively easy to handle
experimentally. In order to know the cellular organization, I examined the expression patternsof several molecular markers in the chick pallium. The molecular markers were chosen fromthe genes specifically expressed in particular cellular layers of mammalian neocortex. As aresult, the expression patterns of those molecular markers in chickens did not show any
obvious layer structure as seen in mammals, though they clearly indicated regional
distinctions. The expressions of markers for mammalian upper cortical layer were located in
the mesopallium of the chick telencephalon and those for the deep layer were in thehyperpallium. From this kind of study, I would speculate the developmental program of thecommon ancestor’s pallium and the evolutionary events, which make the uniqueness of the
mammalian neocortex.
Evolutionary origin of sex-related genes in the mouse brain
Kazuya Yuge, Kazuho Ikeo and Takashi Gojobori
With the aim of elucidating the evolutionary process of sexual
dimorphism in the brain at the molecular level, we conducted genomic
comparisons of a set of genes expressed in a sexually different mannerin the mouse brain with all genes from other species of eukaryotes.
First, we obtained the protein-coding genes whose levels of mRNA
expression in the brain differed between male and female miceaccording to the currently available microarray data, and designatedthese genes operationally as "sex-related genes in the mouse brain".
Next, we estimated the time when these sex-related genes in the mousebrain emerged in the evolutionary process of eukaryotes by examining
the presence or absence of the orthologues in the eukaryotic species
whose genome sequences are available. As a result, we found thatabout 60-75% of sex-related genes in the mouse brain emerged after thedivergence of urochordates and mammals whereas about 50% of all themouse genes emerged during the same period of time. In particular,
about 30% of these sex-related genes in the mouse brain emerged justbefore the evolutionary appearance of bony fish. It looks apparent
that the orthologues of these sex-related genes in the mouse brain
appeared with a larger amount at almost the same time as the emergenceof phenotypic sex differences in the brain. Moreover, 30% of
sex-related genes in the mouse brain that emerged after the divergenceof urochordates showed protein binding functions, compared to none ofthese genes that emerged before the divergence of urochordates. Thesefindings therefore suggest that the formation of new protein-protein
interactions through binding functions in vertebrates may haveinfluenced the evolution of sexual dimorphism in the brain at themolecular level.
Transcriptional interferences in cis natural antisense transcripts of human and mouse
Naoki Osato, Yoshiyuki Suzuki, Kazuho Ikeo, Takashi Gojobori
For a significant fraction of mRNAs, their expression is regulated by other RNAs including
cis natural antisense transcripts (cis-NATs) that are complementary mRNAs transcribedfrom opposite strands of DNA at the same genomic locus. The regulatory mechanism ofmRNA expression by cis-NATs is unknown, though a few possible explanations have been
proposed. To understand this regulatory mechanism, we conducted a large-scale analysisof the currently available data and examined how the overlapping arrangements of cis-NATs

affect their expression level. Here, we show that for both human and mouse the expression
level of cis-NATs decreases as the length of the overlapping region increases. In particular,
the proportions of the highly expressed cis-NATs in all cis-NATs examined were about 36%
and 47% for human and mouse, respectively, when the overlapping region was less than
200 bp. However, both proportions decreased virtually to zero when the overlapping regions
are more than 2,000 bp in length. Moreover, the distribution of the expression level of cisNATs changes according to different types of the overlapping pattern of cis-NATs in the
genome. These results are consistent with the transcriptional collision model for the
regulatory mechanism of gene expression by cis-NATs.
Evolutionary analysis of the blind cavefish of Mexican tetra, Astyanax mexicanus, by cDNA
microarrays
Nobuhiko Tanaka, Shozo Yokoyama, Kazuho Ikeo, Takashi Gojobori
Mexican tetra (Astyanax mexicanus), a single species with eyed surface (surface fish) andeyeless cave (cavefish) dwelling forms, gives unique opportunities for studying the geneticsof speciation processes because the direction of evolutionary processes is known withcertainty: cavefish are derived from surface-dwelling ancestors. In this study, to extensively
find genes that can differentiate evolutionary changes between the surface fish and the
cavefish, we conducted cDNA microarray analyses. Each of the microarrays has 3,070 nonredundant genes from an entire body of an adult surface fish. Target genes for the
microarrays were made from an entire body of each a surface fish and a cavefish. As aresult of four-time array analyses, 209 genes out of the 3,070 genes were found withsignificant differential expression (p-value < 0.01): 122 genes and 87 genes were underexpressed genes and over-expressed genes in the cavefish, respectively. Functional
information on the differentially expressed 209 genes suggested behavioral, physiological,
and morphological changes between the surface fish and the cavefish. The differentiallyexpressed genes with functional information could be candidates for further analyses tounderstand a mechanism of the differences of gene expression pattern between the twodwelling forms. This is the first report that differences of gene expression between thesurface fish and the cavefish are extensively examined throughout a whole body.
Compensatory change of interacting amino acids in the coevolution of transcriptional
coactivator MBF1 and TATA-box binding protein TBP
Qing-Xin Liu, Naomi Nakashima-Kamimura, Kazuho Ikeo, Susumu Hirose and Takashi
GojoborTo elucidate the transcriptional regulation in eukaryotic genome network, it is important tounderstand coevolution of transcription factors, transcriptional coactivators and TATA-box
binding protein TBP. In this study, coevolution of transcriptional coactivator MBF1 and its
interacting target TBP was first evaluated experimentally by examining if compensatory
amino acid changes took place at interacting sites of both proteins. The experiments wereconducted by identifying interaction sites and comparing the amino acids at these sites
among different organisms. Here we provide evidence for compensatory changes oftranscription coactivator and its interacting target, presenting the first report thattranscription coactivator may have undergone coevolution with TBP.
Functional analysis of Drosophila TDF during the neuronal development
Qing-Xin Liu, Kazuho Ikeo, Yasushi Hiromi, Susumu Hirose and Takashi Gojobori
In Drosophila, the tracheas defective (tdf) gene encodes a bZIP protein that required for thedevelopment of trachea, heart, head and neural system. TDF is highly expressed in the cellsof the morphogenetic furrow (MF) region. Loss of TDF function causes defects in the eye
development. Overexpression of TDF in the eye disc induced abnormal eyes. Moreover,overexpression of TDF in the leg disc resulted in lack of tarsus. The targets of tdf
responsible for these responses have not been identified. To identify tdf downstream genes
in a comprehensive manner, we used genome-wide oligonucleotide arrays and analyzed
differential gene expression in wild-type embryos versus tdf mutant embryos. Uponknockout of tdf function, expression of 340 genes decreased and 338 genes increased.

Many of these genes can be assigned to specific aspects of the tracheal and neural systemdevelopment. We also discovered tdf target genes that are likely to play specific roles in
eye morphogenesis.
Functional importance of pathfinding of neurons inferred from evolutionary conservation of
Tbx20
Qing-Xin Liu, Masaki Hiramoto, Hitoshi Ueda, Takashi Gojobori, Yasushi Hiromi and
Susumu Hirose
The T-box transcription factors are a family of developmentally regulated DNA-binding
proteins that play an important role in organogenesis. In fact, they are involved with
developmental processes such as cell lineage choices, terminal differentiation andproliferation. However, the function of T-box transcription factors in neural development ispoorly understood. With the aim of examining functional significance of Tbx20 in theprocess of pathfinding of neurons, we have first identified the midline gene, a Drosophila
ortholog of Tbx20, which is a master control gene for neuronal pathfinding. We thendetermined the binding sequence of Midline using the in vitro binding site selection method.
As a result, we found that the binding sequence of Midline existed in the upstream regions
or an intron of slit, frazzled and robo. Chromatin immunopreciptation also showed that
Midline directed binding of Midline to the binding sites of all three genes. Using
comparative genomics, the binding sequence of Midline was also found in the regulating
regions of slit, frazzled and robo in the genomes of zebrafish, mouse and human. Thus, therole of Tbx20 in the pathfinding of neurons is very much important, because its orthologs ofhuman, mouse and zebrafish are also expressed in motor neurons.
Search for the evolutionary origin of protozoan lens-eye
Shiho Hayakawa, Hwang Jung Shan, Yasuharu Takaku, Satoshi Nagai, Takeo Horiguchi,
Hiroshi Suga, Kazuho Ikeo, Walter Gehring and Takashi Gojobori
The dinoflagellates (division Pyrrhophyta, class Dinophyceae) are a group of unicellular
phytoplankton in marine and fresh waters, which are composed of more than 2,000 species.
More than a half of them are photosynthetic while the rest of them are heterotrophic. One offamilies in dinoflagellates, Warnowiaceae, consists of three heterotrophic genera,
Warnowia, Erythropsis and Nematodinium, which are identified by distinct structures suchas cingulum, sulcus and “ocellus”. In particular, “ocellus” is an organelle of the lens-likestructure which exists only in this family. With the aim of examining if this protozoan lenseye is actually the evolutionary origin of human camera-eyes, we attempted to identify thegenes that may be involved with the formation and function of the ocellus. In practice, wecollected samples of the species for the three genera of Warnowiaceae, which were
carefully identified by morphological traits, from the sea near Japan as well as theMediterranean Sea. Isolating DNAs from those samples, we first confirmed species
identification by constructing molecular phylogenetic tree of SSU rDNAs and mitochondrial
genes. Then, we constructed cDNA libraries and sequenced cDNA clones. When we madethe annotation on those clone sequences, we found that there were homologues forphotoreceptor-related genes such as rhodopsin and plastid-targeting proteins. Moreinterestingly, we also found a number of gene homologues that can be apparently related tomorphogenesis of the ocellus and retina. From these reasons, we think it reasonable toconclude that at least some genes in protozoan ocellus shared the common ancestry withmammalian camera-eyes. The coming issue will be to know by which mechanisms this canbe brought, straightforward evolution or horizontal gene transfer.
To search the origin of neural tube: Gene expression analysis of ciliaryband in sea urchin embryo
Sonoko Kinjo, Kazuho Ikeo and Takashi Gojobori
Sea urchin, a member of echinoderm, has radial nervous system although it isclose relatives of vertebrates that have centralized nervous system. It isbeing accepted that neural tube, the central nervous system (CNS) of
vertebrates, originated from protostome CNS because of the similarity of Hox
genes expression between vertebrates and protostomes. However, this theory

cannot explain how echinoderm establishes its unique nervous system. Because
molecular mechanism of nervous system of sea urchin is largely unknown,
first we investigated the genes concerning nervous system of sea urchin. We
constructed cDNA library of ciliary band, a nervous system of sea urchinlarva, and sequenced around 5,000 expressed sequence tags (ESTs) so far.
For the 1,000 ESTs, annotation via homology search was conducted and 40% of
ESTs matched to known genes. More than half of matched genes were
mitochondrial genes. In the remaining matched genes, there were actin andtubulin that relate to ciliary movement. In addition, we found ESTs thatshows high similarity with BAC clone of sea urchin that contain Hox cluster
genes. At the current situation, there are few genes functionary annotatedenough and 60% of ESTs did not match any known genes. Further we would liketo conduct more detail annotation.
Ancient positive selection on CD155 as a possible cause for susceptibility
to poliovirus infection in simians
Yoshiyuki Suzuki
Poliovirus is the etiological agent of poliomyelitis. From the observations
that only simians are susceptible to poliovirus infection and that 37 aminoacid sites (the poliovirus-binding associated [PBA] sites) in the domain D1of CD155 are involved in the binding to poliovirus, it is considered thatthe susceptibility to poliovirus infection evolved through amino acidsubstitutions that occurred at the PBA sites on the ancestral branch ofsimians. Here it is shown that positive selection has operated on thesesubstitutions by analyzing the nucleotide sequences encoding almost theentire region of D1 in humans, non-human hominoids (chimpanzees andgorillas), Old World monkeys (African green monkeys), New World monkeys(brown capuchins, squirrel monkeys, and marmosets), prosimians (ring-tailed
lemurs), and non-primate mammals (rabbits). Positive selection is unlikely
to have operated on the susceptibility to poliovirus infection, but possiblyon the binding to another molecule. Elimination of susceptibility topoliovirus infection in simians may be difficult, because it also requires
elimination of advantageous effects that have been exerted by CD155.
Natural selection on the influenza virus genome
Yoshiyuki Suzuki
Influenza viruses are the etiological agents of influenza. Althoughvaccines and drugs are available for the prophylaxis and treatment ofinfluenza virus infections, the generation of escape mutants has beenreported. To develop vaccines and drugs that are less susceptible to thegeneration of escape mutants, it is important to understand the evolutionary
mechanisms of the viruses. Here natural selection operating on all theproteins encoded by the H3N2 human influenza A virus genome was inferred bycomparing the numbers of synonymous (dS [DS]) and nonsynonymous (dN [DN])substitutions per site. Natural selection was also inferred for the groupsof functional amino acid sites involved in B-cell epitopes (BCEs), T-cell
epitopes (TCEs), drug resistance, and growth in eggs. The entire region of
PB1-F2 was positively selected, and positive selection also appeared tooperate on BCEs, TCEs, and growth in eggs. The frequency of escape mutant
generation appeared to be positively correlated with the dN/dS (DN/DS)
values for the targets of vaccines and drugs, suggesting that the amino acidsites under strong functional constraint are suitable targets. In
particular, TCEs may represent candidate targets, since the dN/dS (DN/DS)
values were small and negative selection was inferred for many of them.
Statistical properties of the methods for detecting positively selectedamino acid sites

Yoshiyuki Suzuki
Parsimony and Bayesian methods have been developed for detecting positively
selected amino acid sites. It has been reported that the parsimony method
is generally conservative. In contrast, the Bayesian method is known to
identify more positively selected sites than the parsimony method,especially when the number of sequences analyzed is small, although theinterpretation of results obtained from the former method is controversial.
Here I show that the likelihood-ratio test (LRT) of the Bayesian method
corresponds to the parsimony method with window analysis, by analyzing thenucleotide sequences encoding the trans-activator (tax) gene of human T-cell
lymphotropic virus type I (HTLV-I). It is also indicated that in theparsimony method, the test of selective neutrality using the binomial
probability tends to be conservative, but the Monte Carlo simulation isuseful for solving this problem. In addition, in the Bayesian method, thebootstrap method appears to produce similar results to the LRT. This
information may be useful for improving the methods for detecting positively
selected amino acid sites.

RESEARCH ACTIVITIES(1) Intrinsically disordered loops inserted into the structural domains of humanproteins
Fukuchi, S., Homma, K., Minezaki, Y. and Nishikawa, K.
Much attention has been paid recently to proteins with partially or fully disordered structures,
which are found to exist mostly in eukaryotes and are involved mainly in pivotal cellular
processes such as transcriptional regulation, translation and cellular signal transduction.
Long disordered sequences are sometimes inserted within the single structural domains ofproteins, forming loops from the molecular surface. Such intrinsically disordered loops(IDLs) either are invisible in X-ray crystallography, or hamper protein crystallization itself due
to great flexibility. Perhaps because of this, such long disordered sequences have not beencharacterized adequately. Here, we propose an informational method that stringently
identifies IDLs in the structural domains of proteins using the amino acid sequence alone. A
genome-wide survey of human proteins conducted with the method identified 50 IDLcontaining proteins, several of which have experimentally determined 3D structures. Similar
searches in other entirely sequenced organisms revealed that IDLs are prevalent ineukaryotes, while they are much less so in prokaryotes. As there is a statistically significant
coincidence between the boundaries of IDLs and those of exons, we suggest that IDLs
were produced mainly by exon addition in eukaryotes. IDLs are almost always located at thesurface of proteins and are enriched with hydrophilic residues, and IDL-containing proteins
tend to be intracellular. Some of the well-characterized proteins with IDLs illustrate that IDLs
play pivotal roles in the switching of intracellular signaling or regulatory functions, suggestingthat IDL insertion is an effective way to create functionally different domain variants.
(2) Human transcription factors contain a high fraction of intrinsically disorderedregions essential for transcriptional regulation
Minezaki, Y., Homma, K., Kinjo, A.R. and Nishikawa, K.
Human transcriptional regulation factors, such as activators, repressors, and enhancerbinding factors are quite different from their prokaryotic counterparts in two respects: theaverage sequence in human is more than twice as long as that in prokaryotes, while thefraction of sequence aligned to domains of known structure is 31% in human transcription
factors (TFs), less than half of that in bacterial TFs (72%). Intrinsically disordered (ID)regions were identified by a disorder-prediction program, and were found to be in good
agreement with available experimental data. Analysis of 401 human TFs with experimental
evidence from the Swiss-Prot database showed that as high as 49% of the entire sequenceof human TFs is occupied by ID regions. More than half of the human TFs consist of a small
DNA binding domain (DBD) and long ID regions frequently sandwiching unassigned
regions. The remaining TFs have structural domains in addition to DBDs and ID regions.
Experimental studies, particularly those with NMR, revealed that the transactivation domains

in unbound TFs are usually unstructured, but become structured upon binding to theirpartners. The sequences of human and mouse TF orthologues are 90.5% identical despitea high incidence of ID regions, probably reflecting important functional roles played by ID
regions. In general ID regions occupy a high fraction in TFs of eukaryotes, but not inprokaryotes. Implications of this dichotomy are discussed in connection with their functionalroles in transcriptional regulation and evolution.
(3) CRNPRED: highly accurate prediction of one-dimensional protein structure bylarge-scale Critical Random Networks
Kinjo, A.R. and Nishikawa, K.
One-dimensional protein structures such as secondary structures or contact numbers areuseful for three-dimensional structure prediction and helpful for intuitive understanding of thesequence-structure relationship. Accurate prediction methods will serve as a basis for theseand other purposes. We implemented a program CRNPRED which predicts secondary
structures, contact numbers and residue-wise contact orders. This program is based on anovel machine learning scheme called critical random networks. Unlike most conventional
one-dimensional structure prediction methods which are based on local windows of anamino acid sequence, CRNPRED takes into account the whole sequence. CRNPRED
achieves, on average per chain, Q3 = 81% for secondary structure prediction, andcorrelation coefficients of 0.75 and 0.61 for contact number and residue-wise contact order
predictions, respectively. CRNPRED will be a useful tool for computational as well as
experimental biologists who need accurate one-dimensional protein structure predictions.
(4) Gene cluster analysis method identifies horizontally transferred genes with highreliability and indicates that they provide the main mechanism of operon gain ineight species of gamma-proteobacteria
Homma, K., Fukuchi, S., Nakamura, Y., Gojobori, T. and Nishikawa, K.
The formation mechanism of operons remains unresolved: operons may form byrearrangements within a genome or by acquisition of genes from other species, that is,horizontal gene transfer (HGT). One hindrance to its elucidation is the unavailability of amethod to accurately identify HGT, although it is generally considered to occur. It is criticallyimportant first to select horizontally transferred (HT) genes reliably and then to determine theextent to which HGT is involved in operon formation. For this purpose, we considered indels
in terms of gene clusters instead of individual genes and chose candidates of HT genes in 8
species of Escherichia, Shigella, and Salmonella based on the minimization of indels. To
select a benchmark set of positively HT genes against which we can evaluate the candidate
set, we devised another procedure using intergenetic alignments. Comparison with thebenchmark set demonstrated the absence of a significant number of false positives in thecandidate set, showing the high reliability of the method. Analyses of Escherichia coli K-12
operons revealed that although approximately 20 operons were probably gained from thelast common ancestor of the 8 gamma-proteobacteria, deletion of intervening genes
accounts for the formation of no operons, whereas horizontal transfer expanded 2 operons
and introduced 4 entire operons. Based on these observations and reasoning, we suggestthat the main mechanism of operon gain is HGT rather than intragenomic rearrangements.
We propose that genes with related essential functions tend to reside in conserved
operons, whereas genes in nonconserved operons mostly confer slight advantage to theorganisms and frequently undergo horizontal transfer and decay. HT genes constitute atleast 5.5% of the genes in the 8 species and approximately 45% of which originate fromother gamma-proteobacteria. Genes involved in viral functions and mobile andextrachromosomal element functions are HT more often than expected. This finding
indicates frequent mediation of HGT by bacteriophages. On the other hand, not only
informational genes (those involved in transcription, translation, and related processes) but
also operational genes (those involved in housekeeping) are HT less frequently than
expected.
(5) Intrinsically disordered regions of human plasma membrane proteinspreferentially occur in the cytoplasmic segment

Minezaki, Y., Homma, K., and Nishikawa, K.
A systematic survey of intrinsically disordered (ID) regions was carried out in 2109 humanplasma membrane proteins with full assignment of the transmembrane topology withrespect to the lipid bilayer. ID regions with 30 consecutive residues or more were detected
in 41.0% of the human proteins, much higher than the corresponding figure (4.7%) for inner
membrane proteins of Escherichia coli. The domain organization of each of the membraneprotein in terms of transmembrane helices, structural domains, ID and unassigned regions
as well as the distinction of inside or outside of the cell was determined. Long ID regions
constitute 13.3% and 3.5% of the human plasma membrane proteins on the inside andoutside of the cell, respectively, showing that they preferentially occur on the cytoplasmic
side. We interpret this phenomenon as reflection of the general scarcity of ID regions on theextracellular side and their relative abundance on the cytoplasmic side in multicellular
eukaryotic organisms.
(6) A tree of life based on protein domain organizations
Fukami-Kobayashi, K., Minezaki, Y., Tateno, Y. and Nishikawa, K.
It is desirable to estimate a tree of life, a species tree including all available species in thethree superkingdoms, Archaea, Bacteria and Eukaryota, using not a limited number ofgenes but full-scale genome information. Here we report a new method for constructing atree of life based on protein domain organizations, i.e. sequential order of domains in a
protein, of all proteins detected in a genome of an organism. The new method is free fromthe identification of orthologous gene sets and therefore does not require the burdensome
and error-prone computation. By pairwise comparisons of the repertoires of protein domainorganizations of 17 archaeal, 136 bacterial and 14 eukaryotic organisms, we computed
evolutionary distances among them and constructed a tree of life. Our tree showsmonophyly in Archaea, Bacteria and Eukaryota, and then monophyly in each of eukaryotic
kingdoms and in most bacterial phyla. In addition the branching pattern of the bacterial phyla
in our tree is consistent with the widely accepted bacterial taxonomy, and is very close toother genome-based trees. A couple of inconsistent aspects between the traditional trees
and the genome-based trees including ours, however, would perhaps urge to revise theconventional view, particularly on the phylogenetic positions of hyperthermophiles.

Yoshio Tateno
RESEARCH ACTIVITIESThe laboratory consists of five members: Dr. Yoshio Tateno (Professor), Dr. Roberto
Antonio Barrero Gumiel (Assistant Professor), Dr. Atsushi Ogura (Postdoc), Dr. Yasuharu
Takaku (Postdoc) and Ms. Naoko Murakata (Secretary). We aim at the elucidation of theorigin, evolution and function of genes and proteins in view of molecular evolution, structural
biology and information biology in collaboration with other research groups in the instituteand out. Besides the research activities summarized below, we take part in the DDBJ
activity in particular in the database construction and public relations.
RESEARCH ACTIVITY(1) DDBJ in preparation for overview of research activities behind data submissions
Okubo, K., Sugawara, H., Gojobori, T. and Tateno, Y.
In the past year, DDBJ (http://www.ddbj.nig.ac.jp) collected and released 1,956,826 entries
or 1,741,313,111 bases. The released data include approximately 90,000 ESTs andcDNAs of Macaca fascicularis, and 280 million bases of mouse GSS. In addition to thedata collection, we have indexed the submitted data to the International Nucleotide
Sequence Database Collaboration (INSDC, http://www.insdc.org) to classify the entries into
research projects behind data submissions. They are expected to be useful to the datasubmitters and users for enhancing the data submission, retrieval and systematic data
analyses at INSDC. The results of indexing also allow one to grasp research projects in life
sciences that promoted and produced the DNA sequences submitted to INSDC. (Okubo, K.
et al., 2006)(2) Evidence standards in experimental and inferential INSDC Third Party Annotation data.
Cochrane, G., Bates, K., Apweiler, R., Tateno, Y., Mashima, J., Kosuge, T., Mizrachi, I.,
Schafer, S. and Fetchko, M.
The Third Party Annotation (TPA) project collects and presents high-quality annotation of
nucleotide sequence. Annotation is submitted by researchers who have not themselves
generated novel nucleotide sequence. In its first few years, the resource has proven to be
popular with submitters from a range of biological research areas. Central to the project isthe requirement for high-quality data, resulting from experimental and inferred analysis
discussed in peer-reviewed publications. The data are divided into two tiers: those withexperimental evidence and those with inferential evidence. Standards for TPA are detailed
and illustrated with the aid of case studies. (Cochrane, G. et al. 2006)

(3) The concept of sampling in 'omics technology
Morrison, N., Cochrane, G., Faruque, N., Tatusova, T., Tateno, Y., Hancock, D., and Field,
D.
Fundamental biological processes can now be studied by applying the full range of OMICS
technologies (genomics, transcriptomics, proteomics, metabolomics, and beyond) to thesame biological sample. Clearly, it would be desirable if the concept of sample were shared
among these technologies, especially as up until the time a biological sample is preparedfor use in a specific OMICS assay, its description is inherently technology independent.
Sharing a common informatic representation would encourage data sharing (rather thandata replication), thereby reducing redundant data capture and the potential for error. This
would result in a significant degree of harmonization across different OMICS data
standardization activities, a task that is critical if we are to integrate data from thesedifferent data sources. Here, we review the current concept of sample in OMICS
technologies as it is being dealt with by different OMICS standardization initiatives anddiscuss the special role that the newly formed Genomic Standards Consortium (GSC) might
have to play in this domain. (Morrison, N. et al. 2006)(4) Exploration and grading of possible genes in 183 bacterial strains by a common fine
protocol lead to new genes: Gene Trek in Prokaryote Space (GTPS).
Kosuge, T., Abe, T., Okido, T., Tanaka, N., Hirahata, M., Maruyama, Y., Mashima, J.,
Tomiki, A., Kurokawa, M., Himeno, R., Miyazaki, M., Gojobori, T., Tateno, Y., andSugawara,, H.
A large number of the complete genomes for microorganisms have been sequenced andsubmitted to the public database, and then incorporated in our complete genome database,
Genome Information Broker (GIB, http://gib.genes.nig.ac.jp/). When researchers carry out
research in comparative genomics or others, however, they must be aware that there areprotein coding genes not confirmed by homology or motif search, and that reliable protein
coding genes are missing. Therefore, we have developed a protocol (Gene Trek in
Prokaryote Space, GTPS) for finding possible protein coding genes in bacterial genomes.
GTPS is equipped with a protocol for assigning a degree of reliability to predicted protein
coding genes. We then systematically applied it to all complete genomes of 123 bacterial
species and strains that were publicly available as of July 2003 first, and then again those of
183 species and strains available as of September 2004. As a result, we found a number ofwrong genes and several new ones in the genome data in question with respect to thecriteria of GTPS. We also showed a way of estimating the total number of orthologous
genes in the bacterial world. (Kosuge T. et al., 2006)(5) Molecular characterization of developmental gene in eyes: Through data-mining on
integrated transcriptome databases
Choy, K.W., Wang, C. C., Ogura, A., Lau, T. K., Rogers M. S., Ikeo, K., Gojobori, T., Tang,
L. Y., Lam, D. S., Chun, T. K. and Pang, C. P.
Our aim was to utilize publicly available and proprietary sources to discover candidate
genes important for ocular development. DESIGN AND METHODS: The collated
information on our 5092 non-redundant clusters was grouped and functional annotation was
conducted using gene ontology (FatiGO) for categorizing them with respect to molecularfunction. The web-based viewer technological platform (H-InvDB) was employed fortranscription analyses of in-house high quality fetal eye Expressed Sequence Tags (ESTs).
Eye-specific ESTs were also analyzed across species by using EMBEST. RESULTS:
According to adult eye cDNA libraries, nucleic acid binding and cell structure/cytoskeletal
protein genes were the most abundant among the ESTs of fetal eyes. Using cDNA
assembly in H-InvDB, 20 (80%) of the 25 most commonly expressed genes in the human
eye are also expressed in extraocular tissues. The crystalline gamma S gene is highlyexpressed in the eye, but not in other tissues. We used EMBEST to compare human fetal
eye and octopus eye ESTs and the expression similarity was low (1.6%). This indicated that
our fetal eye library contains genes necessary for the developmental process and biological
function of the eye, which may not be expressed in the fully developed octopus eyes. The
human fetal eye cDNA library also contained highly abundant eye tissue genes, includingalphaA-crystallin, eukaryotic translation elongation factor 1 alpha 1 (EEF1A1), bestrophin(VMD2), cystatin C, and transforming growth factor, beta-induced (BIGH3).
CONCLUSIONS: Our annotated EST set provides a valuable resource for gene discovery
and functional genomic analysis. This display will help to appreciate the strengths andweaknesses of the different technological platforms, so that in future studies the maximum
amount of beneficial information can be derived from the appropriate use of each method.
(Choy, K. W. et al., 2006)(6) Development of a method for constructing a phylogenetic tree by using many different
orthologs
Tokumasa Horiike, Daisuke Miyata, Kazuo Hamada, Satoshi Saruhashi, Takao Shinozawa,
Yoshio Tateno
To compare the topologies between a pair of phylogenetic trees, we developed a methodthat can accommodate the difference in the number of OTUs between the pair in question.
This method enables us to extract a common set of phylogenetic relationships that areconsistent among a group of the constructed trees irrespective of the number of OTUs.
Since the one including the largest common set trees among the group is considered toshow the closest phylogenetic relationships to the true ones, we also developed a statisticalmethod to single it out. We are now constructing a dataset of orthologs for bacterial species
to apply the method for elucidating bacterial phylogeny.

RESEARCH ACTIVITIES
1) BodyMap-Xs: Anatomical breakdown of 17 million animal ESTs for cross-species
comparison of gene expression (Ogasawara O, Watanabe K, Imamura H, Iizuka T, Okubo
K)
BodyMap-Xs (http://bodymap.jp) is a database for cross-species gene expression
comparison (Ogasawara, O., et.al., 2006) ; it was created by the anatomical breakdown of
17 million animal EST records in DDBJ by using a sorting program tailored for thispurpose. In BodyMap-Xs, users are allowed to compare the expression patterns oforthologous and paralogous genes in a coherent manner; this will provide valuable insights
for the evolutionary study of gene expression and identification of a responsive motif for aparticular expression pattern. In addition, starting from a concise overview of thetaxonomical and anatomical breakdown of all animal ESTs, users can navigate to obtaingene expression ranking of a particular tissue in a particular animal; this method may leadto the understanding of the similarities and differences between the homologous tissues
across animal species. BodyMap-Xs will be automatically updated in synchronization withthe major update in DDBJ, which occurs periodically.
2) Comparison of human gene expression profiles measured with EST, GeneChip, SAGE
and iAFLP (Ogasawara O, Arikawa K, Watanabe K, Iizuka T, Okubo K) :The practical definition of a transcriptome is a entire population of mRNA in a definedsource, i.e. a cell, cells, tissue, or an organism.
The composition , which gene and how abundant, is central to the transcriptome data.
As an expansion of the world-first gene expression database BodyMap(http://bodymap.jp),
we are collecting gene expression data for human and mouse with newly developed
technique iAFLP (http://okubolab.genes.nig.ac.jp/bodymap_i).
In order to estimate performance (sensitivity, specificity and so on) of the iAFLP and the
BodyMap gene expression profiles and to construct a reference gene expression profile,
we compared these data to the other publicly available gene expression profiles obtainedwith CGAP-SAGE and GeneChip.
3)Machine interpretation of genome-wide measurement data (Okubo K):
Construction of a system for automatic recruitment of biomedical knowledge and machineinterpretation of genome-wide measurement data.

RESEARCH ACTIVITIES
Entry of neural stem cells to the quiescent state.
Takuya Tsuji, Takako Isshiki
We have been studying how Drosophila neural progenitors generate diverse cell types in astereotyped order, changing their characteristics over time. It is known that Drosophila
neural progenitors, called neuroblasts, sequentially express a set of transcription factors,some of which specify temporal identity. However, many parts of the mechanisms regulating
temporal specification in the CNS remain unknown. In the past few years, we have focusedon investigating temporal change of neuroblasts at the late stages of embryogenesis, aswell as during the larval period. Before our study, very little was known about temporalchange of neuroblasts at these late developmental stages, although the change deals with
fundamental aspects of neurogenesis: (1) temporal specification of the late-born neurons
occupying half of the CNS, (2) the quiescence and the reactivation of neuroblast
proliferation, and (3) the size of the CNS. We have been investigating these aspects
genetically by using a model neuroblast lineage. This year, we focused on the timing and themechanism of entering to the quiescent state. We found that a few temporal specifictranscription factors are involved in regulating the entry. In addition, we observed that themodel neuroblast changes its morphology dramatically upon the entry, although it retain
many feature of mitotic neuroblast, such as expression of neuroblast specific genes andcyclinE. This may suggest unknown fundamental aspects of the quiescence.
Asymmetric cell division and temporal change of neuroblasts
Eri Hasegawa, Takako Isshiki
Neuroblasts can change their characteristics over time, in contract, cell fate of ganglion
mother cells, daughters of neuroblast, is largely fixed upon their birth. The asymmetry of
temporal fate specification is the fundamental mechanism to generate diverse cell types via
stem cells, and asymmetric cell division of neuroblast regulated by cortical polarity havebeen extensively investigated. However, how the asymmetry of temporal fate specification
occurs is still unclear. We have been trying to elucidate the problem by studying themechanisms controling asymmetirc pattern of expression of temporal specific transcription
factors.

RESEARCH ACTIVITIESMechanics and dynamics of cell architecture: focusing on the cell nucleus andchromosomes
Akatsuki Kimura
The cell architecture laboratory was founded in June of 2006. The lab aims at understanding
the mechanics and dynamics of cell architecture. A cell can be seen as a sophisticatedarchitecture. The spatial organization of cell architecture is critical for the functions of thecell. The mechanical analysis of cell architecture is a frontier in basic biology and willcontribute to understanding division, differentiation, metabolism, and morphology of the cell.
Mathematical modeling and quantitative measurement are the two major approaches
emphasized in the lab. Mathematical modeling is used to increase the accuracy of
hypothesis-testing by computing the consequences of hypotheses. Quantitative
measurement is crucial for mechanical understanding of cell architecture. The lab isdeveloping various image-processing algorithms to quantitatively measure the position andmorphology of cellular components. Our research will provide a novel strategy to analyze cellarchitecture and thus the mechanisms of cellular functions.
The ongoing research projects in the lab involves (i) construction of mathematical models on
dynamic positioning of chromosomes during the mitotic phase, (ii) quantitative
measurements of subcellular components in the nematode Caenorhabditis elegans
embryos, and (iii) reconstitution of centrosome positioning in vivo, in silico, and in vitro. All
research projects are in progress.

RESEARCH ACTIVITIESThe Technical section supports the research activity of NIG in many fields. For example, we
support the Radioisotope center and Experimental farm, and the Genetic strain research
center where genetic and transgenic strains of mice, rice, flies, and fish are produced,
maintained, and distributed to other institutions. Members of the staff additionally support
many types of experiments in various laboratories, such as developmental, cell, andmolecular genetics. We continually update our technical services through attending thetraining and annual meetings for the technological staffs.
