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.
CC {ECO:0000250|UniProtKB:P35226}.
CC -!- SUBUNIT: Component of a PRC1-like complex. Identified in a PRC1-like
CC HPRC-H complex with CBX2, CBX4, CBX8, PHC1, PHC2, PHC3 RING1 and RNF2.
CC Interacts with RNF2/RING2 (By similarity). Interacts with RING1 (By
CC similarity). Part of a complex that contains RNF2, UB2D3 and BMI1,
CC where RNF2 and BMI1 form a tight heterodimer, and UB2D3 interacts only
CC with RNF2. The complex composed of RNF2, UB2D3 and BMI1 binds
CC nucleosomes, and has activity only with nucleosomal histone H2A.
CC Interacts with CBX7 and CBX8. Interacts with SPOP. Part of a complex
CC consisting of BMI1, CUL3 and SPOP. Interacts with E4F1. Interacts with
CC PHC2 (By similarity). Interacts with zinc finger protein ZNF277 (By
CC similarity). May be part of a complex including at least ZNF277, BMI1
CC and RNF2/RING2 (By similarity). {ECO:0000250|UniProtKB:P25916,
CC ECO:0000250|UniProtKB:P35226}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P35226}. Cytoplasm
CC {ECO:0000250|UniProtKB:P35226}.
CC -!- TISSUE SPECIFICITY: Transcripts are found in thymic lymphomas bearing
CC insertions of the gene. Transcription is low or undetectable in mid-
CC gestational fetal liver, neonatal and adult spleen, and in healthy
CC lymph nodes. {ECO:0000269|PubMed:8390036}.
CC -!- INDUCTION: Down-regulated by oxidative stress.
CC {ECO:0000250|UniProtKB:P25916}.
CC -!- PTM: May be polyubiquitinated; which does not lead to proteasomal
CC degradation. Monoubiquitinated. {ECO:0000250}.
