WebIndeed, H1.2-mediated repression of p53 target genes can be negated by DNA-dependent protein kinase (DNA-PK)-mediated phosphorylation of H1.2 at its threonine 146 residue (T146), which impedes H1.2 binding to p53 (Kim et al. 2012). More research on the PTMs and binding partners of H1.2 is needed to establish a clear understanding of its role in ... WebHistones are basic nuclear proteins responsible for nucleosome structure of the chromosomal fiber in eukaryotes.
