Polycomb complex protein BMI-1

Gene

Bmi1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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. The complex composed of RNF2, UB2D3 and BMI1 binds nucleosomes, and has activity only with nucleosomal histone H2A. In the PRC1-like complex, regulates the E3 ubiquitin-protein ligase activity of RNF2/RING2 (By similarity).By similarity1 Publication

Interactioni

Subunit structurei

Component of a PRC1-like complex (PubMed:16359901). Identified in a PRC1-like HPRC-H complex with CBX2, CBX4, CBX8, PHC1, PHC2, PHC3, RING1 and RNF2 (By similarity). Interacts with RNF2/RING2 (PubMed:16359901, PubMed:16710298). Interacts with RING1 (PubMed:16359901, PubMed:16710298). Part of a complex that contains RNF2, UB2D3 and BMI1, where RNF2 and BMI1 form a tight heterodimer, and UB2D3 interacts only with RNF2. The complex composed of RNF2, UB2D3 and BMI1 binds nucleosomes, and has activity only with nucleosomal histone H2A. Interacts with CBX7 and CBX8 (PubMed:16359901). Interacts with SPOP. Part of a complex consisting of BMI1, CUL3 and SPOP. Interacts with E4F1 (By similarity). Interacts with PHC2 (PubMed:16359901).By similarity2 Publications
