背景
Heterochromatin Protein 1 (HP1) (Chromobox Homolog, CBX) includes three isoforms in mammals, designated α, β, and γ. HP1 proteins are approximately 25 kDa in size. They are highly conserved adapter proteins with important regulatory functi ons in the cell nucleus. These functions include notably gene silencing by heterochromatin formation. HP1 proteins are fundamental units of heterochromatin packaging that are enriched at the centromeres and telomeres of nearly all Eukaryotic chromosomes. HP1β and γ also localize to euchromatic sites in the genome. Members of the HP1 family are characterized by an N-terminal chromodomain and a C-terminal chromoshadow domain, separated by a Hinge region. Chromodomain and chromoshadow domain establish secondary interactions with a large number of other proteins. HP1 proteins are subject to multiple types of post-translational modifications, including phosphorylation, acetylation, methylation, ubiquitination and sumoylation, suggesting multiple means of regulation.
