Phosphorylation histone h1
WebOct 15, 2000 · Dephosphorylation of H1 and H3 are not likely to be the only damage-induced posttranslational modifications of histones. It is likely that multiple modifications (phosphorylation, acetylation, methylation, and ubiquitination) as proposed by Strahl (55) acting in a combinatorial or sequential fashion specify unique downstream functions.

WebMay 3, 2010 · Histone H1 phosphorylation is associated with transcription by RNA polymerases I and II. Histone H1 phosphorylation affects chromatin condensation and … While most histone H1 in the nucleus is bound to chromatin, H1 molecules shuttle between chromatin regions at a fairly high rate. It is difficult to understand how such a dynamic protein could be a structural component of chromatin, but it has been suggested that the steady-state equilibrium within the nucleus still strongly favors association between H1 and chromatin, meaning that despite its dynamics, the v…
WebNov 11, 2005 · The first genome-wide evidence is provided that when phosphorylated at a specific C-terminal domain site i.e serine 187, the linker histone H1.4 is enriched at active promoters, in direct contrast to previous reports that suggest that phosphorylation of H1 leads to their dissociation from chromatin. 4 PDF View 1 excerpt, cites background WebMay 22, 2024 · Conclusions. Our data provide strong evidence that H1 variant interphase phosphorylation is dynamically regulated in a site-specific and gene-specific fashion during pluripotent cell differentiation, and that enrichment of pS187-H1.4 at genes is positively related to their transcription.
