Question: Do A-type lamins bind euchromatin or heterochromatin?

Context:
These data reveal that the domain encoded by exon 9 is important to maintain telomere homeostasis and heterochromatin structure but does not play a role in DNA repair, thus pointing to other exons in the lamin A tail as responsible for the genomic instability phenotype in Lmna(Δ8-11/Δ8-11) mice
Lmna(Δ9/Δ9) MEFs exhibit telomere shortening and heterochromatin alterations but do not activate cathepsin L-mediated degradation of 53BP1 and maintain expression of BRCA1 and RAD51
Lamin A Δexon9 mutation leads to telomere and chromatin defects but not genomic instability
Caspase-6 gene disruption reveals a requirement for lamin A cleavage in apoptotic chromatin condensation
The A- and B-type nuclear lamin networks: microdomains involved in chromatin organization and transcription.
Comparative genomic hybridization (CGH) analyses of microdissected blebs, fluorescence in situ hybridization (FISH), and immunofluorescence localization of modified histones demonstrate that gene-rich euchromatin associates with the LA/C blebs
Lamin A/C, caspase-6, and chromatin configuration during meiosis resumption in the mouse oocyte
Our results demonstrated that these proteins were always present and that their distributions were related to oocyte maturity, determined by chromatin configuration and oocyte diameter
Histone acetylation controls, almost exclusively, euchromatin protein dynamics; lamin A expression regulates heterochromatin protein dynamics, and G9a regulates both euchromatin and heterochromatin protein dynamics.
Histone acetylation controls, almost exclusively, euchromatin protein dynamics; lamin A expression regulates heterochromatin protein dynamics, and G9a regulates both euchromatin and heterochromatin protein dynamics.
Other proteins that reversibly interact with DNA, such as the lamins and nuclear pores, may have a role in the organization of DNA into transcribable euchromatin and nontranscribable heterochromatin.

Role for A-type lamins in herpesviral DNA targeting and heterochromatin modulation.

Answer: These data reveal that the domain encoded by exon 9 is important to maintain telomere homeostasis and heterochromatin structure but does not play a role in DNA repair, thus pointing to other exons in the lamin A tail as responsible for the genomic instability phenotype in Lmna(Δ8-11/Δ8-11) mice
Comparative genomic hybridization (CGH) analyses of microdissected blebs, fluorescence in situ hybridization (FISH), and immunofluorescence localization of modified histones demonstrate that gene-rich euchromatin associates with the LA/C blebs. On the other hand, the domain encoded by exon 9 is important to maintain telomere homeostasis and heterochromatin structure but does not play a role in DNA repair, thus pointing to other exons in the lamin A tail as responsible for the genomic instability phenotype in Lmna(Δ8-11/Δ8-11) mice
Exact answer: Both euchromatin and heterochromatin
