CASP1 protein (His tag), recombinant mouse

Activity: Testing in progress Protein Construction: A DNA sequence encoding the Mouse CASP1 protein (P29452) (Asn 120-Asp 296) was expressed with a N-His tag. Sequence: Asn 120-Asp 296. Fusion tag: N-His Endotoxin: Please contact us for more information. Apparent Molecular Mass: 21 kDa. Protein function: Caspase-1, also known as IL-1 beta -converting enzyme (ICE), is an aspartic protease that plays a key role in the inflammatory response and apoptosis. Caspase-1 precursor (about 50kDa) can be cleaved and the active enzyme consists of a complex of two 20 k Protein function: Thiol protease involved in a variety of inflammatory processes by proteolytically cleaving other proteins, such as the precursors of the inflammatory cytokines interleukin-1 beta (IL1B) and interleukin 18 (IL18) as well as the pyroptosis inducer Gasdermin-D (GSDMD), into active mature peptides (PubMed:21147462, PubMed:32109412). Plays a key role in cell immunity as an inflammatory response initiator: once activated through formation of an inflammasome complex, it initiates a pro-inflammatory response through the cleavage of the two inflammatory cytokines IL1B and IL18, releasing the mature cytokines which are involved in a variety of inflammatory processes (PubMed:21147462). Cleaves a tetrapeptide after an Asp residue at position P1 (PubMed:21147462). Also initiates pyroptosis, a programmed lytic cell death pathway, through cleavage of GSDMD (PubMed:32109412). In contrast to cleavage of interleukins IL1B and IL1B, recognition and cleavage of GSDMD is not strictly dependent on the consensus cleavage site but depends on an exosite interface on CASP1 that recognizes and binds the Gasdermin-D, C-terminal (GSDMD-CT) part (PubMed:32109412). Cleaves and activates CASP7 in response to bacterial infection, promoting plasma membrane repair (PubMed:18667412, PubMed:22464733, PubMed:35705808). Upon inflammasome activation, during DNA virus infection but not RNA virus challenge, controls antiviral immunity through the cleavage of CGAS, rendering it inactive (PubMed:28314590). In apoptotic cells, cleaves SPHK2 which is released from cells and remains enzymatically active extracellularly. [The UniProt Consortium]
