Connecting the DOTs: covalent histone modifications and the formation of silent chromatin.
Histone methylation has emerged as a significant regulator of chromatin structure and function. Two different classes of histone methyltransferase (HMT) have been described, which target either lysine or arginine residues in the histone N-terminal tails. A flurry of recent papers now describe a third class of HMT that affects chromatin silencing indirectly, not by methylation of histone tails, but instead by targeting a conserved lysine residue in the core domain of the nucleosome.
