CST, 8581S, APR3 Antibody

Polyclonal Antibody for studying APR3. Validated for Western Blotting. Highly specific and rigorously validated in-house, APR3 Antibody (CST #8581) is ready to ship. Product Usage Information 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. Protocol Available protocols: Western Blotting Specificity / Sensitivity APR3 Antibody recognizes endogenous levels of total APR3 protein. Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro29 of human APR3 protein (isoform a). Antibodies are purified by protein A and peptide affinity chromatography. Background Apoptosis related protein 3 (APR3), also known as C2orf28, is a membrane protein identified in HL-60 cells treated with all-trans retinoic acid (ATRA) and was later found to be induced by ATRA in other sensitive cell lines (1,2). APR3 is also up-regulated by NFAT and NF-κB activities (3). Regulation of APR3 by ATRA suggests a role in cell differentiation, but the mechanism of action is still unclear. Overexpression of APR3 can inhibit proliferation by inducing G1/S cell cycle arrest and decreasing expression of cyclin D1 (2). APR3 has also been shown to interact with NELL-1 to regulate osteoblast differentiation (4).
