Caspase
From Proteopedia
Template:STRUCTURE 1pyo
Caspase (CASP) are cysteine-aspartic proteases which function in apoptosis, necrosis and inflammation. Twelve CASP have been identified in human. CASP is synthesized as an inactive pro-CASP with a prodomain which is being cleaved off to render them active. The X-linked inhibitor of apoptosis protein (XIAP) with its baculoviral IAP repeat (BIR) domain is an inhibitor of CASP.
- CASP-1 (or Interleukin-1 beta converting enzyme, ICE) cleaves precursor cytokine interleukin 1-β and interleukin 18 into mature protein.
- CASP-3 interacts with CASP-8 and CASP-9 during cell apoptosis.
- CASP-7 is a heterodimer consisting of P20 (human residues 1-198) and P11 (human residues 199-303) subunits. CASP-7 catalytic domain consists of residues 57-303. is an important initiator CASP and drICE is an effector of apoptosis CASP in Drosophila melanogaster.
- Metacaspase (MCASP) are arginine/lysine specific CASP. MCASP are found in plants and fungi.
