Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity A1/Bfl-1 (E4P2I) Rabbit Monoclonal Antibody recognizes endogenous levels of total A1/Bfl-1 protein. A strong band of unknown origin is detected at 28 kDa in some cell lines. Species Reactivity: Mouse, Rat Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of mouse A1/Bfl-1 protein. Background The Bcl-2-related protein A1 (Bfl-1, BCL2A1) is an anti-apoptotic member of the Bcl-2 family originally cloned from mouse bone marrow as a granulocyte macrophage-colony stimulating factor (GM-CSF)-inducible gene (1). Expression of A1/Bfl-1 is primarily restricted to hematopoietic cells, although it has been detected in some non-hematopoietic tissues including lung and in endothelial cells (1,2). A1/Bfl-1 protein is rapidly induced by NF-κB and is elevated in response to a variety of factors that stimulate this pathway, including TNF-α and IL-1β, CD40, phorbol ester, and LPS (2-4). As with other Bcl-2 family proteins, A1/Bfl-1 functions by binding and antagonizing pro-apoptotic members of the family (Bid, Bim), which inhibits release of mitochondrial cytochrome c (5). In contrast, research studies indicate that the enzyme calpain cleaves A1/Bfl-1 at specific sites within the amino-terminal region, creating pro-apoptotic, carboxy-terminal fragments that promote mitochondrial release of cytochrome c and apoptosis (6). Studies suggest a possible therapeutic strategy of targeting apoptosis through use of the specific A1/Bfl-1 cleavage fragments (7).
