Chromatin regulation involves the tightness of packing of DNA. When DNA is tightly packed, gene expression is slower. CHDs contain several domains such as chromodomain which is found in proteins involved in chromatin remodeling, PHD zinc finger which has Cys4-His-Cys3 motif and BRK domain which is associated with chromodomains. CHD1 - ATP-dependent chromatin-modeling factor. Functions as substrate recognition component of the transcription regulatory acetylation complex SAGA. CHD4 - Chromatin-modeling factor. Functions as component of the transcription regulatory deacetylation complex NuRD. See Chromodomain helicase DNA-binding factor 4 (CHD4). CHD5 - belongs to ATP-dependent chromatin remodelling proteins. It is a regulator of a tutor-suppressive network. CHD6 - Probable transcription regulator. CHD7 - ATP-dependent chromatin-modeling factor. May be involved in the 45S precursor ribosomal RNA production. CHD8 - acts as transcription repressor by modeling chromatin structure and recruiting histone H1 to target genes. Histone H3 tail peptide contains trimethyllysine and dimethylarginine (PDB entry 2b2u). 3D structures of Chromodomain-helicase-DNA-binding protein Chromodomain-helicase-DNA-binding protein 3D structures
