Detection of Human cIAP‑1/HIAP‑2 by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line either mock transfected, transfected with full length human cIAP-1, or transfected with full length human cIAP-2, HepG2 human hepatocellular carcinoma cell line, Jurkat human acute T cell leukemia cell line, and A431 human epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Human cIAP‑1/HIAP‑2 Monoclonal Antibody (Catalog # MAB818) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for cIAP‑1/HIAP‑2 at approximately 72 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

cIAP-1 (also known as BIR2, MIHB and HIAP-2) is a member of the inhibitor of apoptosis (IAP) family of proteins that inhibit the proteolytic activity of mature caspases. cIAP-1 has 3 BIR (baculovirus inhibitor of apoptosis) domains, a RING finger domain, and a caspase recruitment domain (CARD). cIAP-1 inhibits caspases by interaction of the BIR domain with the active caspase. Caspase activity may be restored through interactions with the Reaper like motif on mitochondrial proteins such as SMAC/Diablo or HTRA-2/Omi. cIAP-1 is reported to be cleaved by caspases in fetal rat hepatocytes treated with TGF-beta.
