Caspase-5 (CASP5) is a member of the cysteine-aspartic protease (caspase) family, primarily involved in inflammatory signaling and pyroptosis. As part of the inflammatory caspase subfamily (alongside caspase-1. -4. and -11), it is encoded by the *CASP5* gene in humans and shares structural homology with other caspases, featuring a conserved catalytic domain. Unlike apoptotic caspases, CASP5 is activated through inflammasome complexes, which sense pathogen-associated molecular patterns (PAMPs) or danger signals. It exists as an inactive zymogen (procaspase-5) that undergoes proteolytic cleavage to form active subunits (p20 and p10), enabling enzymatic function.
CASP5 plays a critical role in innate immunity by processing pro-inflammatory cytokines like pro-IL-1β and pro-IL-18 into their active forms. It is implicated in the non-canonical NLRP3 inflammasome pathway, where it may collaborate with caspase-4/11 to amplify inflammatory responses. Dysregulation of CASP5 has been linked to chronic inflammatory diseases (e.g., Crohn’s disease), autoimmune disorders, and cancer. For instance, elevated CASP5 expression correlates with poor prognosis in certain cancers, possibly due to its role in tumor-associated inflammation.
Recombinant CASP5 proteins are engineered for in vitro studies to dissect its activation mechanisms, substrate specificity, and interactions with inflammasome components. These proteins are typically produced in *E. coli* or mammalian expression systems, often fused with tags (e.g., His-tag) for purification. Research using recombinant CASP5 has advanced drug discovery, including screening for inhibitors to modulate inflammatory pathways. However, its functional overlap with caspase-1 and caspase-4 complicates studies, necessitating precise molecular tools to delineate its unique contributions. Understanding CASP5 biology remains vital for developing therapies targeting inflammasome-driven diseases. (Word count: 249)
