Background of CBX5 antibody

Heterochromatin protein-1 (HP1) is a methyl-lysine binding protein localized at heterochromatin sites, where it mediates gene silencing. It has been shown that mammalian methyltransferases that selectively methylate histone H3 on lysine-9 generate a binding site for HP1 proteins, a family of heterochromatic adaptor molecules implicated in both gene silencing and supranucleosomal chromatin structure. High-affinity in vitro recognition of a methylated histone H3 peptide by HP1 requires a functiol chromodomain. Thus, the HP1 chromodomain is a specific interaction motif for the methyl epitope on lysine-9 of histone H3. In vivo, heterochromatin association of HP1 proteins is lost in Suv39h double- primary mouse fibroblasts but is restored after reintroduction of a catalytically active SUV39H1 HMTase. A molecular mechanism through which the SUV39H-HP1 methylation system can contribute to the propagation of heterochromatic subdomains in tive chromatin has been defined. It has been demonstrated that HP1 can bind with high affinity to histone H3 methylated at lysine-9 but not at lysine-4. The chromodomain of HP1 as its methyl-lysine-binding domain has been identified. A point mutation in the chromodomain, which destroys the gene silencing activity of HP1 in Drosophila, abolished methyl-lysine-binding activity. Genetic and biochemical alysis in S. pombe showed that the methylase activity of Clr4 (the SUV39H1 homolog) is necessary for the correct localization of Swi6 (the HP1 equivalent) at centromeric heterochromatin and for gene silencing. A stepwise model for the formation of a transcriptiolly silent heterochromatin: SUV39H1 places a methyl marker on histone H3, which is then recognized by HP1 through its chromodomain has been suggested. This model may also explain the stable inheritance of the heterochromatic state. SUV39H1 and HP1 are both involved in the repressive functions of the retinoblastoma protein. Rb associates with SUV39H1 and HP1 in vivo by mean
