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 ). 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 ...
