Secondry Information

Protein Function Caspases are members of cysteinyl dependent aspartate directed proteases family which plays essential roles in regulating apoptosis at cellular level, and finally causes cellular demise through a cascade of molecular events; involved in disassembly of the cells into apoptotic bodies during apoptosis; member of the apoptosis executioner group
Biochemical Properties intracellular proteases; activation is also appears to be associated with the increased mitochondrial transmembrane potential; Optimal pH for caspase-3 is 7.4; activity is relatively stable between 0 and 150 mM NaCl; caspases lose over 40% of their activity upon removal of CHAPS from the buffer, and the effect is more dramatic with caspase-6 than with caspases-3; active over a broader pH range with an optimum slightly higher than the other caspases; there is a faster than expected drop-off in activity at low pH, most clearly observed with caspases-3 and -6
Significance in milk PMNs isolated from milk of mastitic cows showed revealing activities of caspase-3 which indicated that the milk PMNs undergo induced apoptosis and the process is programmed via the activation of initiator and executioner caspases
PTMs phosphorylation at the highly conserved position S150; PKCd phosphorylates caspase-3 at S26; DEVD phosphorylates at the +3 (P3) position
Significance of PTMs negatively controlled by p38 MAPK in neutrophils via phosphorylation at the highly conserved position S150; PKCd enhances caspase-3 activity and increase apoptotic cell death; DEVD promotes proteolysis of procaspase-3 by caspase-8 , demonstrating a functional significance of caspase-3 activation through phosphorylation for the execution step of apoptosis
