[https://www.uniprot.org/uniprot/CBX4_HUMAN CBX4_HUMAN] E3 SUMO-protein ligase which facilitates SUMO1 conjugation by UBE2I. Involved in the sumoylation of HNRNPK, a p53/TP53 transcriptional coactivator, hence indirectly regulates p53/TP53 transcriptional activation resulting in p21/CDKN1A expression.<ref>PMID:12679040</ref> <ref>PMID:16061479</ref> <ref>PMID:17018294</ref> <ref>PMID:21282530</ref> <ref>PMID:22825850</ref> 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.<ref>PMID:12679040</ref> <ref>PMID:16061479</ref> <ref>PMID:17018294</ref> <ref>PMID:21282530</ref> <ref>PMID:22825850</ref> | |||
