| Background Information | The Bmi1 protein is a member of the polycomb group (PcG) proteins. PcG proteins form multiprotein complexes that function as transcriptional repressors. Several lines of evidence implicate Bmi1 in tumorigenesis. Firstly, Bmi1 cooperates with c-Myc in the generation of lymphomas in double transgenic mice. Secondly, Bmi1 blocks senescence and immortalizes mouse embryo fibroblasts, although not human fibroblasts, and in combination with an activated H-ras gene leads to neoplastic transformation. Thirdly, the BMI1 gene is amplified in certain mantle cell lymphomas and is overexpressed in a subset of non-small cell lung cancer, colorectal carcinomas, multiple myelomas and medulloblastomas, but not glioblastomas. Fourthly, the transformation of human hematopoietic progenitor cells by the oncogenic fusion protein E2a-Pbx1 requires Bmi1. Indeed, based on a list of genes differentially expressed in a mouse model of metastatic prostate cancer on a wild-type and bmi1-deficient genetic background a gene signature was recently identified that may predict response to therapy and survival in multiple types of cancer. |

| UniProt Summary | FUNCTION: SwissProt: P35226 # Component of the Polycomb group (PcG) multiprotein PRC1 complex, a complex 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. SIZE: 326 amino acids; 36949 Da SUBUNIT: Component of chromatin-associated class II polycomb repressive complex 1 (PRC1/hPRC-H) at least composed of PCGF2/RNF110, BMI1/PCGF4, CBX2/M33, CBX4/PC2, CBX8/PC3, PHC1, PHC2, PHC3, SCMH1, RING1 and RNF2/RING2. Also component of E3 ubiquitin ligase complex or human polycomb repressive complex 1- like at least composed of PHC2, BMI1, RING1 and RNF2. Interacts with SPOP. Part of a complex consisting of BMI1, CUL3 and SPOP. SUBCELLULAR LOCATION: Nucleus. PTM: May be polyubiquitinated; which does not lead to proteasomal degradation.DISEASE:SwissProt: P35226 # Cooperates with the MYC oncogene to produce B-lymphomas. SIMILARITY: SwissProt: P35226 ## Contains 1 RING-type zinc finger. |
