Phosphorylation des histones
WebSep 15, 2003 · Cells protect their DNA by organising it as a higher-order nucleoprotein complex termed chromatin in which the basic unit is the nucleosome. Each nucleosome is composed of an octamer of core histones (two each of H2A, H2B, H3 and H4), around which two super-helical turns (80 base pairs) of DNA are wrapped (van Holde, … WebRecent research on histone phosphorylation has demonstrated that nearly all histone types are phosphorylated at specific residues and that these modifications act as a critical intermediate step in chromosome condensation during cell division, transcriptional regulation, and DNA damage repair.
