Interestingly, another recent study suggests that H3.3 may also repress the activities of a subset of ERVs, mostly the intracisternal A particle (IAP) [18].
Web4 de mai. de 2015 · H3.3 is a replication-independent H3 histone variant in mammalian systems that is enriched at both H3K4me3- and H3K27me3-marked bivalent genes as well as H3K9me3-marked endogenous retroviral ... Web3 de ago. de 2024 · If H3.3 directly represses ERVs, ERV upregulation in H3.3-knockout ES cells and H3.3 enrichment at these elements in wild-type ES cells should be positively correlated.
Weblated histone H3 and MeCP2 (1, 7), the latter being a MBD protein known to associate with HDAC-containing co-repressor complexes (10). This finding suggests a methylation-dependent mechanism for retroviral silencing in MEL cells that involves specific recruitment of HDACs to methylated DNA through MBD proteins.
