Livin Antibody Summary

A synthetic peptide corresponding to amino acids 180-230 of human Livin, isoform alpha and isoform beta was used as immunogen (NP_647478).
Livin is a short-lived protein that is thought to be degraded by the ubiquitin-proteasome pathway. Thus users may want to do a time course when examining the effects of treatments on Livin expression. Users are encouraged to refer to the literature for additional information; for example, Ma et al. 2006. 2. Livin has been shown to undergo proteolytic cleavage during apoptosis. Thus the molecular weight of Livin observed on Western blots may vary depending on the presence of absence of cleavage fragments.

Livin (BIRC7/KIAP) is a member of the family of inhibitor of apoptosis proteins (IAP) and contains a single copy of a baculovirus IAP repeat (BIR) as well as a RING-type zinc finger domain (reviewed in Ma et al 2006 and Crnkovic-Mertens et al 2006). Resistance towards apoptosis is a hallmark of cancer cells, and overexpression of IAPs can contribute to the development of cancer though inhibiting apoptosis (reviewed in Wright et al. 2005). IAP proteins inhibit apoptosis by binding to and inhibiting caspases through their BIR domain(s). Some IAP members, like Liven, also have a RING-type finger motif at their carboxyl-terminal which may enhance anti-apoptotic activity. Many RING finger-containing IAPs possess E3 ubiquitin ligase activity, and it has been shown that Liven acts an E3 ubiquitin ligase for targeting the degradation of Smac/DIABLO. Smac/DIABLO functions by inhibiting IAP-caspase interactions, thereby promoting apoptosis. Thus, degradation of Smac/DIABLO is thought to be a mechanism to enhance Livin anti-apoptotic activity, thereby promoting cell survival. Two splicing variants of Livin, alpha and beta, have been identified. The two isoforms are thought to have different anti-apoptotic properties; however, there are conflicting reports are to whether they actually differ in their biological activities. There is accumulating evidence that Liven plays a significant role in a spectrum of tumor types and it is thought that Liven may have potential as a diagnostic and prognostic tumor marker. Liven is expressed at low levels in adult tissues, and relatively higher levels in developmental tissues and in many cancer cells. Certain cancer patients develop autoantibodies against liven and in a number of cancers, Livin is detected only in the tumors but not, or to substantially lower levels, in the corresponding normal adjacent tissue. This antibody recognizes Livin, both isoform alpha and isoform beta. Human Livin isoform alpha is a 298 amino acid (aa) protein, GenBank no. NP_647478. Human Livin isoform beta is a 280 aa protein, GenBank no. NP_071444.1. The antibody will also recognize other isoforms of Livin that contain the peptide immunogen sequence.
