WebApr 11, 2024 · Histone H1 phosphorylation is involved in DNA replication, and CDK1/CycB is mainly responsible for histone H1 phosphorylation during mitosis (Gurley et al. 1995). Studies have shown that histone H1 is essential for metaphase chromosome aggregation (Th'ng et al. 1994). Histone H1 phosphorylation is also involved in gene transcription.
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.
