NCIt synonyms : Inhibitor of Apoptosis Protein; IAP Protein;
NCIt definition : A family of proteins that are related structurally and functionally and are inhibitors
of apoptosis.;
NCIt note : IAP Family Proteins exhibit an N-terminal domain containing 1-3 repeats of a 65-70-aa
Cys- and His-rich BIR motif and often a zinc-binding RING finger. Some IAPs inhibit
apoptosis by regulating ICE-like protease activation signals and/or inhibit serum
deprivation-induced apoptosis. Some IAP proteins may bind to TRAF1 and TRAF2. IAP
proteins are frequently over expressed in cancers and associated with resistance to
therapy. (NCI);
