BIRC7. also known as survivin, is a member of the inhibitor of apoptosis (IAP) protein family, characterized by its dual role in regulating cell survival and division. Encoded by the BIRC7 gene, this 16.5 kDa protein contains a single baculovirus IAP repeat (BIR) domain critical for its anti-apoptotic function and a coiled-coil domain that facilitates protein-protein interactions. Unlike other IAPs, survivin is uniquely involved in both apoptosis inhibition and mitotic progression, primarily through binding to chromosomal passenger complex (CPC) components during cell division.
Originally identified for its overexpression in cancer cells, survivin is virtually undetectable in most differentiated tissues but becomes markedly upregulated in various malignancies, including breast, lung, and colorectal cancers. Its oncogenic potential stems from two mechanisms: suppression of caspase-mediated apoptosis through direct interaction with executioner caspases, and regulation of microtubule dynamics during mitosis to ensure proper chromosomal segregation. Additionally, survivin participates in angiogenesis by stabilizing hypoxia-inducible factors in tumor microenvironments.
Recombinant BIRC7 protein is typically produced in bacterial or eukaryotic expression systems for research and therapeutic development. Its purified form enables structural studies, inhibitor screening, and functional assays investigating cancer biology. In drug discovery, survivin-targeting strategies using recombinant protein include designing small-molecule inhibitors, antisense oligonucleotides, and immunotherapies like survivin-directed vaccines. Recent studies also explore its potential as a prognostic biomarker in liquid biopsies.
Despite promising applications, challenges persist in targeting survivin due to its complex cellular localization and dual functionality. Current research focuses on isoform-specific regulation and combination therapies to overcome treatment resistance. The protein's cancer-specific expression profile continues to make it a compelling target for precision oncology approaches.
