Phosphorylation of histone tails
WebPhosphorylation of histones H1 and H3 was discovered in the context of chromosome condensation during meiosis. Phosphorylation of Ser10 on H3 is mediated by ribosomal protein S6kinase 2, which is downstream of extracellular signal–regulated kinase, and phosphorylation of Ser28 on H3 is mediated by aurora kinases. View chapter on ClinicalKey WebAs the DNA moves in and out of its 1.65 turns around the nucleosome, a histone linker, H1, binds to it. Nucleosomes are subject to post-translationally changeable acting on histone N-terminal tails . The modifications include methylation, acetylation, phosphorylation, ribosylation, ubiquitination and sumoylation [26,27]. These modifications are ...
