Chromodomain
From Wikipedia, the free encyclopedia
A chromodomain a is protein structural domain of about 40-50 amino acid residues commonly found in proteins associated with the remodeling and manipulation of chromatin. The domain is highly conserved among both plants and animals, and is represented in a large number of different proteins in many genomes, such as that of the mouse. Some chromodomain-containing genes have multiple alternative splicing isoforms that omit the chromodomain entirely.[1] In mammals, chromdomain-containing proteins are responsible for aspects of gene regulation related to chromatin remodeling and formation of heterochromatin regions.[2] Chromodomain-containing proteins also bind methylated histones[3][4] and appear in the RNA-induced transcriptional silencing complex.[5]
