The inhibitor of apoptosis (IAP) family of proteins regulates programmed cell death triggered by various stimuli. All IAPs have at least one baculovirus IAP repeat (BIR) motif that is essential for their anti-apoptotic activity. Recently, Kasof and Gomes , Vucic et al. and Ashhab et al. have identified a novel human inhibitor of apoptosis protein (IAP) family member termed Livin or ML-IAP, which contains a single baculoviral IAP repeat (BIR) domain and a COOH-terminal RING finger domain. Livin gene has two splicing variants that contain open reading frames of 298 and 280 amino acids and both contained a single copy of baculovirus IAP repeat (BIR) and RING domain. Both of the isoforms inhibit TNFa induced apoptosis in Jurkat cells. Livin expression is low in adult tissues. It is relatively expressed at a higher level in developmental tissues and in many cancer cells. A novel member in the IAP protein family was recently identified and designated Livin and KIAP for kidney IAP. Livin/XIAP contains a single baculoviral IAP repeat (BIR) domain and a RING finger domain and has two isoforms termed Livin-a and Livin-b. Transfection of Livin in cells resulted in protection from apoptosis induced by FADD, BAX, RIP, RIP3 and DR6. Livin has direct interaction with several caspases including caspase-3, -7, and -9. Livin inhibits the activation of caspase-9 induced by Apaf-1, cytochrome c, and dATP. The two isoforms of Livin appear to have different functions and tissue distributions.
