Gene Symbol Cbx8
Protein Name chromobox homolog 8 (Drosophila Pc class)
Synonyms Pc3;
Species Mus musculus
Ensembl Protein ENSMUSP00000026663
InnateDB Gene IDBG-214668 (Cbx8)
Protein Structure
UniProt Annotation
Function Component of a Polycomb group (PcG) multiprotein PRC1- like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility (By similarity). {ECO:0000250}.
Subcellular Localization Nucleus.
