CC -!- FUNCTION: Component of a Polycomb group (PcG) multiprotein PRC1-like
CC complex, a complex class required to maintain the transcriptionally
CC repressive state of many genes, including Hox genes, throughout
CC development. PcG PRC1 complex acts via chromatin remodeling and
CC modification of histones; it mediates monoubiquitination of histone H2A
CC 'Lys-119', rendering chromatin heritably changed in its expressibility.
CC The complex composed of RNF2, UB2D3 and BMI1 binds nucleosomes, and has
CC activity only with nucleosomal histone H2A. In the PRC1-like complex,
CC regulates the E3 ubiquitin-protein ligase activity of RNF2/RING2 (By
CC similarity). {ECO:0000250|UniProtKB:P35226,
CC ECO:0000269|PubMed:16710298}.
CC -!- SUBUNIT: Component of a PRC1-like complex (PubMed:16359901). Identified
CC in a PRC1-like HPRC-H complex with CBX2, CBX4, CBX8, PHC1, PHC2, PHC3,
CC RING1 and RNF2 (By similarity). Interacts with RNF2/RING2
CC (PubMed:16359901, PubMed:16710298). Interacts with RING1
CC (PubMed:16359901, PubMed:16710298). Part of a complex that contains
CC RNF2, UB2D3 and BMI1, where RNF2 and BMI1 form a tight heterodimer, and
CC UB2D3 interacts only with RNF2. The complex composed of RNF2, UB2D3 and
CC BMI1 binds nucleosomes, and has activity only with nucleosomal histone
CC H2A. Interacts with CBX7 and CBX8 (PubMed:16359901). Interacts with
CC SPOP. Part of a complex consisting of BMI1, CUL3 and SPOP. Interacts
CC with E4F1 (By similarity). Interacts with PHC2 (PubMed:16359901).
CC Interacts with zinc finger protein ZNF277 (PubMed:20808772). May be
CC part of a complex including at least ZNF277, BMI1 and RNF2/RING2
CC (PubMed:20808772). {ECO:0000250|UniProtKB:P35226,
