[[ | [[https://www.uniprot.org/uniprot/BIRC5_HUMAN BIRC5_HUMAN]] 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. Isoform 2 and isoform 3 do not appear to play vital roles in mitosis. Isoform 3 shows a marked reduction in its anti-apoptotic effects when compared with the displayed wild-type isoform.<ref>PMID:10626797</ref> <ref>PMID:9859993</ref> <ref>PMID:12773388</ref> <ref>PMID:16322459</ref> <ref>PMID:16291752</ref> <ref>PMID:18591255</ref> <ref>PMID:20826784</ref> <ref>PMID:21536684</ref> [[https://www.uniprot.org/uniprot/INCE_HUMAN INCE_HUMAN]] Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. Probably acts through association with AURKB or AURKC. Seems to bind directly to microtubules. Controls the kinetochore localization of BUB1.<ref>PMID:15316025</ref> <ref>PMID:12925766</ref> <ref>PMID:16760428</ref> [[https://www.uniprot.org/uniprot/BOREA_HUMAN BOREA_HUMAN]] Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. In the complex, it may be required to direct the CPC to centromeric DNA. Major effector of the TTK kinase in the control of attachment-error-correction and chromosome alignment.<ref>PMID:15260989</ref> <ref>PMID:15249581</ref> <ref>PMID:16571674</ref> <ref>PMID:18243099</ref> | ||
