**Background of BIRC8 Recombinant Protein**
BIRC8 (Baculoviral IAP Repeat-Containing Protein 8), also known as ILP-2 or Inhibitor of Apoptosis Protein (IAP)-like Protein 2. belongs to the IAP family, which regulates apoptosis, inflammation, and cellular signaling. IAPs are characterized by conserved Baculoviral IAP Repeat (BIR) domains that mediate protein interactions and inhibit caspases, key enzymes in apoptosis. Unlike well-studied IAPs like XIAP or cIAP1/2. BIRC8 remains less understood, partly due to its restricted expression patterns and evolutionary divergence.
BIRC8 is unique among IAPs as it contains a single BIR domain and lacks a canonical RING finger domain, which typically confers E3 ubiquitin ligase activity in other IAPs. This structural difference suggests distinct regulatory mechanisms. Studies indicate BIRC8 may suppress apoptosis by directly binding caspases or modulating pathways like NF-κB. Its expression is detected in specific tissues, including the placenta and testis, and aberrant levels are linked to cancers, though its role as oncogenic or tumor-suppressive remains debated.
Recombinant BIRC8 protein is engineered for in vitro studies to elucidate its molecular interactions, structural features, and functional roles. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), it enables biochemical assays, caspase inhibition studies, and screening for therapeutic compounds targeting IAP pathways. Research on BIRC8 could advance understanding of apoptosis regulation and inform strategies for treating cancers or inflammatory diseases, though further validation of its physiological relevance is needed.
