FunctionBIRC5_MOUSE Multitasking protein that has dual roles in promoting cell proliferation and preventing apoptosis. Component of a chromosome passage protein complex (CPC) which is essential for chromosome alignment and segregation during mitosis and cytokinesis. Acts as an important regulator of the localization of this complex; directs CPC movement to different locations from the inner centromere during prometaphase to midbody during cytokinesis and participates in the organization of the center spindle by associating with polymerized microtubules. The complex with RAN plays a role in mitotic spindle formation by serving as a physical scaffold to help deliver the RAN effector molecule TPX2 to microtubules. May counteract a default induction of apoptosis in G2/M phase. The acetylated form represses STAT3 transactivation of target gene promoters. May play a role in neoplasia. Inhibitor of CASP3 and CASP7 (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe coupling of apoptosis (programmed cell death) to the cell division cycle is essential for homeostasis and genomic integrity. Here, we report the crystal structure of survivin, an inhibitor of apoptosis, which has been implicated in both control of cell death and regulation of cell division. In addition to a conserved N-terminal Zn finger baculovirus IAP repeat, survivin forms a dimer through a symmetric interaction with an intermolecularly bound Zn atom located along the molecular dyad axis. The interaction of the dimer-related C-terminal alpha helices forms an extended surface of approximately 70 A in length. Mutagenesis analysis revealed that survivin dimerization and an extended negatively charged surface surrounding Asp-71 are required to counteract apoptosis and preserve ploidy. These findings may provide a structural basis for a dual role of survivin in inhibition of apoptosis and regulation of cell division. Crystal structure and mutagenic analysis of the inhibitor-of-apoptosis protein survivin.,Muchmore SW, Chen J, Jakob C, Zakula D, Matayoshi ED, Wu W, Zhang H, Li F, Ng SC, Altieri DC Mol Cell. 2000 Jul;6(1):173-82.
