Chromodomains are highly conserved sequence motifs that have been identified in a variety of animal and plant species. A chromodomain harbours a methylated lysine residue. Chromodomain proteins appear to be either structural components of large macromolecular chromatin complexes, or proteins involved in remodelling the chromatin structure. Some chromodomains have a binding affinity for histone H3 methylated on lysine 9, whereas others have RNA binding capacity.
