ID:BMI1_HUMAN DESCRIPTION: RecName: Full=Polycomb complex protein BMI-1; AltName: Full=Polycomb group RING finger protein 4; AltName: Full=RING finger protein 51; FUNCTION: 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. In the PRC1 complex, it is required to stimulate the E3 ubiquitin-protein ligase activity of RNF2/RING2. SUBUNIT: Component of a PRC1-like complex. Interacts with RING1 and RING2 (By similarity). Interacts vwith CBX7 and CBX8. Interacts with SPOP. Part of a complex consisting of BMI1, CUL3 and SPOP. Interacts with E4F1. INTERACTION: O00257-3:CBX4; NbExp=2; IntAct=EBI-2341576, EBI-4392727; O95503:CBX6; NbExp=2; IntAct=EBI-2341576, EBI-3951758; O95931:CBX7; NbExp=5; IntAct=EBI-2341576, EBI-3923843; Q9HC52:CBX8; NbExp=6; IntAct=EBI-2341576, EBI-712912; Q06587:RING1; NbExp=5; IntAct=EBI-2341576, EBI-752313; Q99496:RNF2; NbExp=5; IntAct=EBI-2341576, EBI-722416; Q9H270:VPS11; NbExp=2; IntAct=EBI-2341576, EBI-373380; SUBCELLULAR LOCATION: Nucleus. Cytoplasm. PTM: Monoubiquitinated (By similarity). May be polyubiquitinated; which does not lead to proteasomal degradation. MISCELLANEOUS: The hPRC-H complex purification reported by PubMed:12167701 probably presents a mixture of different PRC1-like complexes. SIMILARITY: Contains 1 RING-type zinc finger.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
