| Intruduction: | Human Baculoviral IAP repeat-containing protein 5 (BIRC5) gene encodes a multitasking protein that has dual roles in promoting cell proliferation and preventing apoptosis. It is a component of a chromosome passage protein complex (CPC) which is essential for chromosome alignment and segregation during mitosis and cytokinesis. It 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. It is 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. BIRC5 may counteract a default induction of apoptosis in G2/M phase. The acetylated form of BIRC5 represses STAT3 transactivation of target gene promoters. IT may play a role in neoplasia and also 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. Recent data indicated that anti-BIRC5 auto-antibodies can be detected in some cancer patients. Full-length human BIRC5 cDNA (141aa, Isoform-I) was constructed with codon optimization gene synthesis and expressed with a human alpha Fetal Protein N-terminal (AFPn) -His-TEV cleavage site Tag (217aa) fusion at its N-terminal. It was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. |
