Chromobox protein homolog 5 is a protein that in humans is encoded by the CBX5 gene.[1][2]

Heterochromatin protein-1 (HP1) is a methyl-lysine binding protein localized at heterochromatin sites, where it mediates gene silencing.[supplied by OMIM][2]

Interactions[edit]

CBX5 (gene) has been shown to interact with HDAC9,[3] Ku70,[4] MIS12,[5] Lamin B receptor,[6] MBD1,[7][8] TAF4,[9] Histone deacetylase 5,[3] TRIM28,[10][11][12][13] HDAC4,[3] CBX3,[12] SMARCA4,[10] DNMT3B,[14] CHAF1A,[8][13] CBX1[12] and SUV39H1.[3][7][15]
