Caspase-1/CASP1 is a thiol protease complex involved in inflammation by catalyzing the cleavage of IL1B, IL18, and Gasdermin-D (GSDMD). It activates a pro-inflammatory response, releases mature cytokines IL1B and IL18, and initiates pyroptosis through cleavage of GSDMD. Caspase-1/CASP1 Protein, Human (GST) is the recombinant human-derived Caspase-1/CASP1 protein, expressed by E. coli , with N-GST labeled tag. The total length of Caspase-1/CASP1 p20 Protein, Human (GST) is 150 a.a., with molecular weight of ~43.8 kDa.

Human

Caspase-1/CASP1 subunit p10 Protein, a thiol protease, intricately participates in various inflammatory processes by catalyzing the proteolytic cleavage of precursor proteins associated with inflammation. This includes interleukin-1 beta (IL1B) and interleukin 18 (IL18), pivotal inflammatory cytokines, as well as the pyroptosis inducer Gasdermin-D (GSDMD), converting them into active mature peptides. Functioning as a key initiator of cell immunity, Caspase-1 activates a pro-inflammatory response upon inflammasome complex formation, leading to the release of mature cytokines IL1B and IL18, which play critical roles in diverse inflammatory pathways. Caspase-1's activity extends to initiating pyroptosis, a programmed lytic cell death pathway, by cleaving GSDMD. Notably, unlike its cleavage of interleukins, the recognition and cleavage of GSDMD depend on an exosite interface on CASP1, emphasizing its versatile and complex regulatory roles. Moreover, Caspase-1 activates CASP7 in response to bacterial infection, promoting plasma membrane repair, and controls antiviral immunity by cleaving CGAS upon inflammasome activation during DNA virus infection. In apoptotic cells, Caspase-1 cleaves SPHK2, which remains enzymatically active extracellularly. Despite its involvement in diverse cellular processes, Caspase-1 is apoptosis inactive.
