Androgen and glucocorticoid receptors interact with insulin degrading enzyme
Creators: name: KUPFER, S.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: We recently identified a protein, designated receptor accessory factor (RAF), that interacts directly with and enhances the DNA binding of androgen (AR) and glucocorticoid (GR) receptor peptide fragments. To determine its identity, RAF was purified from HeLa cell extracts by anion-exchange and DNA affinity chromatography. RAF activity co-purified with a 110-kDa protein, the partial amino acid sequence of which shares 97.5% identity with insulin degrading enzyme (IDE), a metalloendoprotease implicated in the intracellular degradation of insulin.

gender identity

description: Transgender people in the United States are more likely to experience worse overall health than cisgender (non-transgender) people. Within the U.S. transgender population, differences in expressions of gender identity are linked to health disparities. In social interactions, people typically ascribe gender to others by using cues from embodied characteristics associated with sex differences, such as voices, body shape, and hair growth patterns. Voices, particularly gendered voices, can shape relative social advantage and disadvantage. In this brief, PRC postdoctoral fellow Danya Lagos isolates the link between voice-based gender misclassification and patterns of health inequality within the transgender population. She finds that for both transgender women and transgender men, being perceived as a woman over the phone is associated with worse overall health.
Association of Utrophin and Multiple Dystrophin Short Forms with the Mammalian Mr 58,000 Dystrophin-associated Protein (Syntrophin)

description: Electric tissue syntrophin, originally described as an M(r) 58,000 postsynaptic protein having homologs in mammalian muscle, was previously shown to associate with dystrophin in Triton extracts of Torpedo postsynaptic membranes. It also associates with the Torpedo M(r) 87,000 postsynaptic protein (87K), the core of which is a superdomain homologous to the cysteine-rich (CR) and COOH-terminal (CT) domains of human dystrophin. Using immunoaffinity purifications from various rat tissues and immunoblotting, we find that syntrophin associates with dystrophin, utrophin (the chromosome 6-encoded dystrophin homolog formerly known as dystrophin-related protein), multiple proteins which are cross-reactive with 87K, and two subfamilies of 71K-like proteins (CRCT-containing proteins encoded by the dystrophin gene under the control of an alternative promoter in intron 62). One 71K subfamily retains the dystrophin COOH-terminal sequence; the other has an alternative COOH-terminal sequence caused by deletion of the penultimate exon by alternative splicing. The relative masses of the members of the subfamilies suggest they arise by alternative splicing at other previously described sites within CT. These results establish that syntrophin is a general ligand for the CRCT domain in mammalian dystrophin and its homologs. They also reveal a greater diversity in 71K proteins than has previously been apparent.
Is telegraph noise a good model for the environment of mesoscopic systems?

description: Some papers represent the environment of a mesosopic system (e.g. a qubit in a quantum computer or a quantum junction) by a neighboring fluctuator, which generates a fluctuating electric field -- a telegraph noise (TN) -- on the electrons in the system. An example is a two-level system, that randomly fluctuates between two states with Boltzmann weights determined by an effective temperature. To consider whether this description is physically reasonable, we study it in the simplest example of a quantum dot which is coupled to two electronic reservoirs and to a single fluctuator. Averaging over the histories of the TN yields an inflow of energy flux from the fluctuator into the electronic reservoirs, which persists even when the fluctuator's effective temperature is equal to (or smaller than) the common reservoirs temperature. Therefore, the fuluctuator's temperature cannot represent a real environment. Since our formalism allows for any time dependent energy on the dot, we also apply it to the case of a non-random electric field which oscillates periodically in time. Averaging over a period of these oscillations yields results which are very similar to those of the TN model, including the energy flow into the electronic reservoirs. We conclude that both models may not give good representations of the true environment.

Beta-turn formation in the processing region is important for efficient maturation of Escherichia coli maltose-binding protein by signal peptidase I in vivo.

description: Signal peptidase I (also called leader peptidase) is the endopeptidase that removes the signal peptides of most secreted proteins during or after translocation in Escherichia coli. Precursor recognition is contingent in part on the presence of small, uncharged residues in the -3 and -1 positions relative to the cleavage site, and may also depend on the structure of the processing region. Most precursor processing regions include residues likely to form a beta-turn. Mutations were introduced into the processing region of maltose-binding protein (MBP) that altered the prediction of beta-turn formation in this region. MBP species with a decreased probability of beta-turn formation were processed slowly or not at all, whereas MBP species with an increased probability of beta-turn formation were processed efficiently. Mutations altering the prediction of beta-turn formation in the MBP processing region were also made in cis to a proline in the +1 position. Cleavage at the normal processing site is blocked by proline in the +1 position; this MBP species, MBP27-P, inhibits processing of other proteins by signal peptidase I. Decreasing the probability of beta-turn formation in the processing region of MBP27-P eliminated the inhibition of signal peptidase I, and these MBP27-P derivatives remained unprocessed, suggesting that the formation of a beta-turn in the MBP processing region was necessary for recognition by signal peptidase I. Increasing the probability of beta-turn formation in cis to proline at +1 in MBP did not alter recognition of the protein by the processing enzyme. The results presented here are consistent with the hypothesis that the efficiency of recognition and processing by signal peptidase I is increased by the formation of a beta-turn in the processing region of the MBP signal peptide.

description: Pyrimidine (6-4) pyrimidone photoproduct is the second most abundant UV photoproduct in DNA. Recently, it was reported that Drosophila melanogaster cell-free extracts restored the biological activity of (6-4) photo-product-containing DNA in a light-dependent reaction (Todo, T., Takemori, H., Ryo, H., Ihara, M., Matsunaga, T., Nikaido, O., Sato, K., and Nomura, T. (1993) Nature 361, 372-374) concomitant with the loss of (6-4) photoproduct antigenic sites and (6-4) photoproduct-caused alkali-labile sites. In the present study we show that the (6-4) photoproduct but not its Dewar isomer is the substrate for the enzyme, that the enzyme has an action spectrum peak at 400 nm, and that the efficiency of repair per incident photon is very low compared with cyclobutane pyrimidine dimer photolyases. Furthermore, we provide evidence that the (6-4) photoproduct photolyase converts the photoproduct to unmodified bases probably through an oxetane intermediate.

description: Due to the coherence of all the protons in a nucleus, there are very strong electromagnetic fields of short duration in relativistic heavy ion collisions. They give rise to quasireal photon-photon and photon-nucleus collisions with a large flux. RHIC will begin its experimental program this year and such types of collisions will be studied experimentally at the STAR detector. RHIC will have the highest flux of (quasireal) photons up to now in the GeV region. At the LHC the invariant mass range available in gamma-gamma-interactions will be of the order of 100 GeV, i.e., in the range currently available at LEP2, but with a higher gamma-gamma-luminosity. Therefore one has there also the potential to study new physics. (Quasireal) photon-hadron (i.e., photon-nucleus) interactions can be studied as well, similar to HERA, at higher invariant masses. Vector mesons can be produced coherently through photon-Pomeron and photon-meson interactions in exclusive reactions such as A+A -> A+A+V, where A is the heavy ion and V=rho,omega,phi or J/Psi.

Year: 1994

description: Human cells remove bulky adducts from DNA by excising single-stranded fragments 27-29 nucleotides in length by an enzyme system consisting of at least 14 polypeptides. All of the previous work on characterizing the excision reaction was conducted with plasmids 3 or 8 kilobases in length. To determine if the size and tertiary structure of DNA play a role in the excision reaction and to find out if large DNA fragments are necessary to contact all of the subunits of the excinuclease, we performed experiments with circular DNA and with linear DNA fragments of various sizes. We found that the human excinuclease is capable of removing DNA adducts from linear and covalently closed circular DNAs with about the same efficiency.

description: A direct link between the topological complexity of ferromagnetic media and their dynamics has recently been established through the construction of unambiguous conservation laws as moments of a topological vorticity. In the present paper we carry out this program under completely realistic conditions, with due account of the long-range magnetostatic field and related boundary effects. In particular, we derive unambiguous expressions for the linear and angular momentum in a ferromagnetic film which are then used to study the dynamics of magnetic bubbles under the influence of an applied magnetic-field gradient. The semi-empirical golden rule of bubble dynamics is verified in its gross features but not in its finer details. A byproduct of our analysis is a set of virial theorems generalizing Derrick's scaling relation as well as a detailed recalculation of the fundamental magnetic bubble.

description: Context. Kepler observations have revealed a class of short period exoplanets, of which Kepler-1520 b is the prototype, which have comet-like dust tails thought to be the result of small, rocky planets losing mass. The shape and chromaticity of the transits constrain the properties of the dust particles originating from the planet's surface, offering a unique opportunity to probe the composition and geophysics of rocky exoplanets. Aims. We aim to approximate the average Kepler long-cadence light curve of Kepler-1520 b and investigate how the optical thickness and transit cross-section of a general dust tail can affect the observed wavelength dependence and depth of transit light curves. Methods. We developed a new 3D model that ejects sublimating particles from the planet surface to build up a dust tail, assuming it to be optically thin, and used 3D radiative transfer computations that fully treat scattering using the distribution of hollow spheres (DHS) method, to generate transit light curves between 0.45 and 2.5 $μ$m. Results. We show that the transit depth is wavelength independent for optically thick tails, potentially explaining why only some observations indicate a wavelength dependence. From the 3D nature of our simulated tails, we show that their transit cross-sections are related to the component of particle ejection velocity perpendicular to the planet's orbital plane and use this to derive a minimum ejection velocity of 1.2 kms$^{-1}$. To fit the average transit depth of Kepler-1520 b of 0.87%, we require a high dust mas-loss rate of 7 $-$ 80 M$_\oplus$ Gyr$^{-1}$ which implies planet lifetimes that may be inconsistent with the observed sample. Therefore, these mass-loss rates should be considered to be upper limits.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: In Saccharomyces cerevisiae Ydj1p, a DnaJ homolog, is localized to the cytosol with the Ssa and Ssb Hsp70 proteins. Ydj1p helps facilitate polypeptide translocation across mitochondrial and endoplasmic reticulum membranes (Caplan, A. J., Cyr, D. M., and Douglas, M. G. (1992) CeLL 71, 1143-1155) and can directly interact with Ssa1p to regulate chaperone activity (Cyr, D. M., Lu, X., and Douglas, M. G. (1992) J. Biol. Chem. 287, 20927-20931). In this study, the role of Ydj1p in modulating ATP-dependent reactions catalyzed by Ssa and Ssb Hsp70 proteins has been examined using purified components and compared with that of other Hsp70 homologs BiP and DnaK. Ssalp, Ssa2p, and Ssb1/2p all formed stable complexes with the mitochondrial presequence peptide, F1β(1-51).

description: Gaia Data Release 2 includes observational data for 14,099 pre-selected asteroids. From the sparsely sampled G band photometry, we derive lower-limit lightcurve amplitudes for 11,665 main belt asteroids in order to provide constraints on the distribution of shapes in the asteroid main belt. Assuming a triaxial shape model for each asteroid, defined through the axial aspect ratios a > b and b=c, we find an average b/a=0.80+-0.04 for the ensemble, which is in agreement with previous results. By combining the Gaia data with asteroid properties from the literature, we investigate possible correlations of the aspect ratio with size, semi-major axis, geometric albedo, and intrinsic color. Based on our model simulations, we find that main belt asteroids greater than 50 km in diameter on average have higher b/a aspect ratios (are rounder) than smaller asteroids. We furthermore find significant differences in the shape distribution of main belt asteroids as a function of the other properties that do not affect the average aspect ratios. We conclude that a more detailed investigation of shape distribution correlations requires a larger data sample than is provided in Gaia Data Release 2.

Effect of the secondary structure in the Euglena gracilis chloroplast ribulose-bisphosphate carboxylase/oxygenase messenger RNA on translational initiation.
Creators: name: Spremulli, Linda L
name: Koo, Ja Seok
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: The results reported in the previous paper indicate that the translational start site of the Euglena gracilis chloroplast mRNA for the large subunit of ribulose-bisphosphate carboxylase/oxygenase (rbcL) is not defined by primary sequence elements (Koo, J.S., and Spremulli, L.L. (1994) J. Biol. Chem. 269, 7494-7500). In the work presented here, the effects of secondary structure in the 5'-untranslated leader of the rbcL mRNA have been examined. Only weak secondary structure can be detected in the 5'-untranslated leader of the rbcL message by enzymatic and computer analysis. Further reduction of the weak secondary structure of this message by site-directed mutagenesis does not significantly affect the ability of this message to participate in initiation complex formation. The secondary structure near the translational start site was increased by the introduction of an inverted repeat sequence and by site-directed mutagenesis. Messages with increased secondary structure are much less active in initiation complex formation if the structural element introduced is within approximately 10 nucleotides of the start codon. These results suggest that the translational start site in this chloroplast mRNA is specified by the presence of an AUG codon in an unstructured or weakly structured region of the mRNA. No specific sequences around the start codon, either upstream or immediately downstream, were found to have important information directing the chloroplast ribosome to the start site of this mRNA.

description: We derive evolution equations satisfied by moments of parton distributions when the integration over the Bjorken variable is restricted to a subset (x_0 <= x <= 1) of the allowed kinematical range 0<= x<= 1. The corresponding anomalous dimensions turn out to be given by a triangular matrix which couples the N--th truncated moment with all (N + K)--th truncated moments with integer K >= 0. We show that the series of couplings to higher moments is convergent and can be truncated to low orders while retaining excellent accuracy. We give an example of application to the determination of alpha_s from scaling violations.

In particular, we prove the action $π_1(X)\timesπ_n(X)\toπ_n(X)$ fails to be continuous for a one-point union $X=A\vee \mathbb{H}_n$ where $A$ is an aspherical space such that $π_1(A)$ is a topological group and $\mathbb{H}_n$ is the $(n-1)$-connected, n-dimensional Hawaiian earring space $\mathbb{H}_n$ for which $π_n(\mathbb{H}_n)$ is a topological abelian group.

Escherichia coli DNA helicase I catalyzes a sequence-specific cleavage/ligation reaction at the F plasmid origin of transfer.
Creators: name: Sherman, J A
name: Matson, S W
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: Recent studies have shown that the Escherichia coli F plasmid-encoded traI gene product (TraIp), also known as DNA helicase I, catalyzes the formation of the site- and strand-specific nick that initiates F plasmid DNA transfer. Scission of the phosphodiester bond at the nic site within the origin of transfer (oriT) is accompanied by the covalent attachment of TraIp to the 5'-phosphate of the nicked DNA strand. This mechanism suggests that TraIp may also be capable of catalyzing a DNA ligation reaction using the energy stored in the protein-DNA intermediate. To test this possibility, an in vitro assay was designed that utilized short single-stranded DNA oligonucleotides of different lengths derived from the region within oriT that spanned the nic site. Purified TraIp was capable of efficiently cleaving single-stranded DNA that contained a nic site, and upon cleavage, the protein became covalently linked to the 5'-end of the nic site. When TraIp was incubated with two oligonucleotides of different length that contained the nic site, there was formation of novel recombinant products resulting from a TraIp-catalyzed cleavage/ligation reaction. Furthermore, the cleavage and ligation reactions were both sequence-specific. These data suggest that TraIp plays an important role in the initiation and termination of conjugative DNA transfer.
Searching for New Physics with Deep Autoencoders

description: We introduce a potentially powerful new method of searching for new physics at the LHC, using autoencoders and unsupervised deep learning. The key idea of the autoencoder is that it learns to map "normal" events back to themselves, but fails to reconstruct "anomalous" events that it has never encountered before. The reconstruction error can then be used as an anomaly threshold. We demonstrate the effectiveness of this idea using QCD jets as background and boosted top jets and RPV gluino jets as signal. We show that a deep autoencoder can significantly improve signal over background when trained on backgrounds only, or even directly on data which contains a small admixture of signal. Finally we examine the correlation of the autoencoders with jet mass and show how the jet mass distribution can be stable against cuts in reconstruction loss. This may be important for estimating QCD backgrounds from data. As a test case we show how one could plausibly discover 400 GeV RPV gluinos using an autoencoder combined with a bump hunt in jet mass. This opens up the exciting possibility of training directly on actual data to discover new physics with no prior expectations or theory prejudice.

Extended junctional sarcoplasmic reticulum of avian cardiac muscle contains functional ryanodine receptors

description: The ryanodine receptor (RYR)/Ca2+ release channel of avian cardiac muscle was localized by immunocytochemical techniques and biochemically characterized using isolated membrane and receptor protein fractions. Monoclonal antibody C3-33 raised against the canine cardiac RYR bound to the junctional sarcoplasmic reticulum of pigeon and finch hearts, both at peripheral couplings and at extended junctional sarcoplasmic reticulum (EJSR). Immunoblots of sarcoplasmic reticulum vesicles from pigeon and finch hearts showed this antibody recognized a single high molecular weight protein, which co-migrated with the canine M(r) 565,000 RYR/Ca2+ release channel polypeptide. The pigeon heart RYR bound [3H]ryanodine with high affinity in a Ca(2+)-dependent manner, comparable to the canine cardiac RYR. Purification of the pigeon RYR yielded a 30 S protein complex, which bound the maximum calculated amount of [3H]ryanodine ((440 +/- 60) pmol/mg protein), assuming one high affinity site/tetrameric 30 S RYR comprised of M(r) 565,000 polypeptides. Autoradiography of isolated finch cardiac myocytes indicated [3H]ryanodine binding throughout the cells. These results suggest that avian heart contains a single population of RYRs, and thereby support the hypothesis that avian EJSR contains functional calcium release channels which, because of the absence of transverse tubules, can be located micrometers away from the surface membrane in avian heart.
