Dna vs histone methylation

Author: rpok

August undefined, 2024

The fundamental unit of chromatin, called a nucleosome, contains DNA wound around a protein octamer. This octamer consists of two copies each of four histone proteins: H2A, H2B, H3, and H4. Each one of these proteins has a tail extension, and these tails are the targets of nucleosome modification by methylation. DNA activation or inactivation is largely dependent on the specific tail residue methylated and its degree of methylation. Histones can be methylated on lysine (K) an… WebControl of CpNpG DNA methylation by the kryptonite histone H3 methyltransferase. Nature 416, 556–560 (2002) doi:10.1038/nature731 (link to article)
