The heterochromatin protein 1 (HP1) family, which consists of three isoforms HP1? (CBX5), HP1? (CBX1) and HP1? (CBX3) are chromatin-associated proteins involved in gene regulation and heterochromatin formation.{20846} CBX proteins have an N-terminal chromodomain, a C-terminal chromoshadow domain, and a hinge domain which connects the two.{23468} Extensive post-translational modifications have been observed and mapped on the CBX proteins.{23471} The chromodomain of CBX5 has been shown to recognize di- and tri-methylated lysine 9 on histone H3 (H3K9me2 and H3K9me3), with a preference for H3K9me3. Binding of CBX5 to methylated histones leads to gene silencing and heterochromatin formation.{20846,20874} H3K9 trimethylation by the methyltransferase SETDB1 creates a binding site for recruitment of CBX5, leading to chromatin condensation and gene silencing.{20845} The chromoshadow domain facilitates protein-protein interactions like homodimerization and recruitment of nuclear proteins involved in transcriptional regulation.{20843} The chromoshadow domain is also responsible for recruitment to sites of DNA damage, where CBX5 helps to reorganize chromatin as part of the DNA damage response system.{20844}
