Protein Name: Chromobox protein homolog 3

UniprotKB/SwissProt ID: CBX3_MOUSE (P23198)

Gene Name: Cbx3

Organism: Mus musculus (Mouse).

Function: Component of heterochromatin. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. Probably involved in the repression of many genes located in euchromatin, such as E2F1, MYC and CDC25A. Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins (By similarity).

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Nucleus. Note=May be associated with microtubules and mitotic poles during mitosis (Potential). Associates with euchromatin and is largely excluded from constitutive heterochromatin.
