Overview
XIAP an apoptotic suppressor protein. Inhibist apoptosis through binding to tumor necrosis factor receptor-associated factors TRAF1 and TRAF2. Inhibits apoptosis induced by menadione, a potent inducer of free radicals, and ICE. Inhibits cell-death proteases, caspase-3, caspase-7, and perhaps caspase-9. Note: This description may include information from UniProtKB.
Protein type: EC 6.3.2.-; Apoptosis; Ligase; Ubiquitin conjugating system; Ubiquitin ligase
Chromosomal Location of Human Ortholog: Xq25
Cellular Component: cytoplasm; nucleus; cytosol
Molecular Function: protein binding; zinc ion binding; caspase inhibitor activity; ubiquitin-protein ligase activity; ligase activity
Biological Process: Wnt receptor signaling pathway; apoptosis; positive regulation of protein ubiquitination; regulation of inflammatory response; regulation of BMP signaling pathway; protein ubiquitination; negative regulation of caspase activity; response to DNA damage stimulus; copper ion homeostasis; regulation of cell proliferation; negative regulation of apoptosis; regulation of innate immune response
