Summaries for CASP1 Gene

Entrez Gene Summary for CASP1 Gene

  • This gene encodes a protein which is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce 2 subunits, large and small, that dimerize to form the active enzyme. This gene was identified by its ability to proteolytically cleave and activate the inactive precursor of interleukin-1, a cytokine involved in the processes such as inflammation, septic shock, and wound healing. This gene has been shown to induce cell apoptosis and may function in various developmental stages. Studies of a similar gene in mouse suggest a role in the pathogenesis of Huntington disease. Alternative splicing results in transcript variants encoding distinct isoforms. [provided by RefSeq, Mar 2012]

GeneCards Summary for CASP1 Gene

CASP1 (Caspase 1) is a Protein Coding gene. Diseases associated with CASP1 include Cowpox and Legionellosis. Among its related pathways are Gene Expression and p53 Signaling. GO annotations related to this gene include peptidase activity and cysteine-type peptidase activity. An important paralog of this gene is CASP5.

UniProtKB/Swiss-Prot for CASP1 Gene

  • Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.

Tocris Summary for CASP1 Gene

  • Caspases (cysteinyl aspartate proteases) are involved in the signaling pathways of apoptosis, necrosis and inflammation. These enzymes can be divided into initiators and effectors. The initiator isoforms are activated by, and interact with, upstream adaptor molecules.

    404 amino acids
    Molecular mass:
    45159 Da
    Quaternary structure:
    • Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (p20) and a 10 kDa (p10) subunit. The p20 subunit can also form a heterodimer with the epsilon isoform which then has an inhibitory effect. May be a component of the inflammasome, a protein complex which also includes PYCARD, CARD8 and NALP2 and whose function would be the activation of proinflammatory caspases. Both the p10 and p20 subunits interact with MEFV. Interacts with CARD17/INCA and CARD18.
