靶标信息
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 . Involved in the recruitment of CPC to centromeres during early mitosis via association with histone H3 phosphorylated at ‘Thr-3’ (H3pT3) during mitosis . 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 .
