Protein Information (annotations from UniProt)

Database IDHIV0002156
UniProt IDQ8NDX5
Primary gene name(s)PHC3
Synonym gene name(s)EDR3, PH3
Protein namePolyhomeotic-like protein 3
Protein functionComponent 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. {ECO:0000269|PubMed:12167701}.
Subcellular locationNucleus {ECO:0000269|PubMed:12167701, ECO:0000269|PubMed:21282530}.
