Molecular Weight (kDa) | 23 |
Source/Isotype | Rabbit |
Application/Dilution | {Western Blotting: 1:1000} |
Storage | Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody. |
Specificity/Sensitivity | Puma Antibody detects endogenous levels of total Puma protein. The antibody also cross-reacts with an 18kDa band of unknown origin. |
Species Reactivity | Human |
Source/Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal region of human Puma. Antibodies are purified by protein A and peptide affinity chromatography. |
Background | Puma (p53 upregulated modulator of apoptosis) is a "BH3-only" Bcl-2 family member originally identified in differential gene expression studies as a p53-inducible gene (1,2). The "BH3-only" family members include Bad, Bid, Bik, Hrk, Bim, and Noxa, all of which contain a BH3 domain but lack other conserved domains, BH1 and BH2, and generally promote apoptosis by binding to and antagonizing anti-apoptotic Bcl-2 family members through BH3 domain interactions (3). Two BH3-containing proteins are produced from the puma gene, Puma-α and Puma-β, both of which are induced by p53, bind Bcl-2 and Bcl-xL, localize to the mitochondria, and promote cytochrome c release and apoptosis (1,2). Puma plays a critical role in the p53 tumor suppressor pathway. Targeted disruption of the puma gene impairs p53-mediated apoptosis and tumor suppression (4-7). Puma knockout mice show defects from multiple apoptotic stimuli, including ionizing irradiation, deregulated c-Myc expression, and cytokine withdrawal (4). |
