XAF1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 161 amino acids (1-125) and having a molecular mass of 18.6 kDa.XAF1 is fused to a 36 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
XIAP Associated Factor 1 (XAF1) is a protein which binds to and counteracts the inhibitory effect of a member of the IAP (inhibitor of apoptosis) protein family. IAP proteins bind to and inhibit caspases which are activated in the course of apoptosis. The ratio of IAPs and proteins which interfere with their activity, such as the XAF1 protein, influence the progress of the apoptosis signaling pathway. Additionally, XAF1 inhibits anti-caspase activity of BIRC4. XAF1 induces cleavage and inactivation of BIRC4 independent of caspase activation. Furthermore, XAF1 mediates TNF-alpha-induced apoptosis and is involved in apoptosis in trophoblast cells.
