Heterochromatin protein-1 (HP1) is a methyl-lysine binding protein localized at heterochromatin sites, where it mediates gene silencing. Mammalian methyltransferases that selectively methylate histone H3 on lysine-9 generate a binding site for HP1 proteins, which are adaptor molecules involved in gene silencing and chromatin structure. High-affinity recognition of methylated histone H3 by HP1 requires a functional chromodomain, making it a specific interaction motif for the methyl epitope on lysine-9. In vivo, heterochromatin association of HP1 proteins is lost in Suv39h double-primary mouse fibroblasts but restored after reintroduction of catalytically active SUV39H1 HMTase.
