Caspase-1 from Human, Recombinant
Cat No.
NATE-0813
Description
Caspase 1/Interleukin-1 converting enzyme is an enzyme that proteolytically cleaves other proteins, such as the precursor forms of the inflammatory cytokines interleukin 1β and interleukin 18, into active mature peptides. Caspase 1 has been shown to induce cell necrosis or pyroptosis and may function in various developmental stages. Studies of a similar protein in mouse suggest a role in the pathogenesis of Huntington's disease. Alternative splicing of the gene results in five transcript variants encoding distinct isoforms. Recent studies implicated caspase 1 in promoting CD4 T-cell death and inflammation by HIV, two signature events that fuel HIV disease progression to AIDS.
