General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

Polycomb complex protein BMI-1 (UniProt: P35226; also known as Polycomb group RING finger protein 4, RING finger protein 51) is encoded by the BMI1 (also known as PCGF4, RNF51) gene (Gene ID: 100532731) in human. BMI-I (B cell-specific Moloney murine leukemia virus integration site 1) is a component of the polycomb repressive complex 1 (PRC1) that is required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. This complex acts via chromatin remodeling and modification of histones and mediates mono-ubiquitination of histone H2A lysine 119, rendering chromatin. The canonical PRC1 complex consists of four core subunits: CBX (polycomb; CBX2/4/6/7/8), PCGF (polycomb group factors; PCGF1 6), PHC (polyhomeotic homologues; PHC1/2/3), and RING E3 ligase (RING1A/B). BMI-I has three domains. The N-terminal RING domain, a central domain, and a C-terminal proline-rich domain. The RING domain forms a complex with RINGA/B proteins that constitutes the heterodimeric E3 ubiquitin ligase subunit of the PRC1 complex. The central is a ubiquitin-like (UBL) domain and is involved in protein-protein interactions and its binding partners include the polyhomeotic proteins (PHC1, PHC2, PHC3). The central domain of BMI-I is reported to be essential for its oncogenic activity and is shown to be essential for transcriptional repression activity. Higher expression of BMI1 gene is overexpressed in certain mantle cell lymphomas and several other cancers. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Gray, F., et al. (2016). Nat. Commun. 7; 13343).
