WebJun 9, 2006 · A prominent modification of H1 is its cell cycle-dependent phosphorylation ( Talasz et al., 1996 ). It has been proposed that this phosphorylation of H1, by cyclin-dependent kinases (CDKs), controls the level of chromatin condensation as cells traverse the cell cycle ( Roth and Allis, 1992 ). WebApr 11, 2024 · Rationale: Human pluripotent stem cell-derived CMs (iPSC-CMs) are a valuable tool for disease modeling, cell therapy and to reconstruct the CM maturation process and identify, characterize factors that regulate maturation.

WebHistone phosphorylation. Histone phosphorylation is targeted to serines (S), threonines (T) and tyrosines (Y) residues on histone proteins. Proteins containing phospho-binding sites such as 14-3-3 and BRCT domains can recognize phosphorylated histones and are involved in downstream effector functions. Phosphorylation on serine (S)139 of the ...
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… dustin hoffman mortWebOct 1, 1999 · Phosphorylation of H1, probably by p34 cdc2 kinase, occurs at specific S or T residues in diverse organisms ( 31 ); it is often associated with cell proliferation and is cell cycle regulated in mammalian cells.
