NCIt synonyms : X-linked Inhibitor of Apoptosis; X-Linked IAP; Apoptosis Inhibitor 3; X-Linked Inhibitor of Apoptosis Protein; IAP-Like Protein; Inhibitor of Apoptosis Protein 3; BIRC4; HILP; Baculoviral IAP Repeat-Containing Protein-4; ILP; EC 2.3.2.27; hIAP3; Baculoviral IAP Repeat-Containing Protein 4; EC 6.3.2.-, Formerly; hIAP-3; RING-Type E3 Ubiquitin Transferase XIAP; IAP-3;
NCIt definition : Baculoviral IAP repeat-containing protein 4 (497 aa, 57 kDa) is encoded by the human
XIAP gene. This protein plays a role in both protein ubiquitination and the inhibition
of apoptosis.;
NCIt note : Encoded BIRC4 Gene (IAP Family), Baculoviral IAP Repeat-Containing Protein 4 inhibits
apoptosis through binding to TNF Receptor-associated factors TRAF1 and TRAF2. Similar
to BIRC2, BIRC4 inhibits apoptosis induced by menadione, a potent inducer of free
radicals, and ICE. BIRC4 also specifically inhibits cell-death proteases, caspase-3
and caspase-7. A novel transcript homologous to BIRC4 is expressed solely in the testis.;
