Anti-Caspase 3 Antibody

产品说明

一般描述

Caspase-3 (UniProt: P42574; also known as EC:3.4.22.56, CASP-3, Apopain, Cysteine protease CPP32, CPP-32, Protein Yama, SREBP cleavage activity 1, SCA-1) is encoded by the CASP3 (also known as CPP32) gene (Gene ID: 836) in human. Cysteine-aspartic proteases or Caspases play essential roles in apoptosis, necrosis, and inflammation. Historically, caspases were numbered in the order in which they were identified. Caspase-3 is a heterotetrameric enzyme that consists of two anti-parallel arranged heterodimers, each one formed by a 17 kDa (p17) and a 12 kDa (p12) subunit. Caspase-3 is initially produced with a propeptide sequence (aa 1-9), the removal of which yields the 268 aa. caspase-3 proenzyme. Upon activation, the proenzyme is proteolytically cleaved first between Asp175-Ser176 to generate a p20 (aa 10-175) fragment and the p12 (aa 176-277) subunit. Further cleavage of the p20 fragment between Asp28-Ser29 produces the p17 (aa 29-175) subunit. The p17 and p12 subunits dimerize and forms the active caspase-3 enzyme. Caspase-3 has a strict requirement for an Asp residue at positions P1 and P4. It has a preferred cleavage sequence of Asp-Xaa-Xaa-Asp-|- with a hydrophobic amino-acid residue at P2 and a hydrophilic amino-acid residue at P3, although Val or Ala are also accepted at this position. Caspase-3 is involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis, it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a Asp216-|-Gly217 bond. Caspase-3 mediates the proteolytic activation of caspases-6 and -7, while caspase-3 itself is processed and activated by caspase-8, -9, or -10.
