Product Specific Information

Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.

Affinity purified Anti-RING1B antibody is directed against human RING1B protein. A BLAST analysis was used to suggest reactivity with this protein from human, chimpanzee, orangutan, mouse, rat, dog, bovine, frog and chicken based on 100% homology for the immunogen sequence. Expect cross reactivity with RING1B from zebrafish, as only a single amino acid residue changes within the immunogen sequence (92% positive by BLAST). Cross reactivity with RING1B homologues from other sources has not been determined.

Target Information

RNF2 (E3 ubiquitin-protein ligase RING2) is a ligase that mediates monoubiquitination of Lys-119 of histone H2A (H2AK119Ub). Therefore, it plays a central role in histone code and gene regulation. The ligase activity is enhanced by BMI1/PCGF4. H2AK119Ub gives a specific tag for epigeneti transcriptional repression and participates in X chromosome inactivation of female mammals. RNF2 may be involved in the initiation of both imprinted and random X inactivation. RNF2 is also an essential component of a Polycomb group (PcG) multiprotein PRC1-like complex. This complex class is required to maintain the transcriptionally repressive state of many genes including Hox genes throughout development. The PcG PRC1 complex acts via chromatin remodeling and modification of histones and rendering chromatin heritably changed in its expressibility.
