Description
Description: Caspase-7 (CMH-1, Mch3, ICE-LAP3) has been identified as a major contributor to the execution of apoptosis (1-4). Caspase-7, like caspase-3, is an effector caspase that is responsible for cleaving downstream substrates such as (ADP-ribose) polymerase and PARP (1, 3). During apoptosis, caspase-7 is activated through proteolyticprocesssing by upstream caspases at Asp23, Asp198, and Asp206 to produce the mature subunits (1, 3). Similar to caspases-2 and-3, caspase-7 preferentially cleaves substrates following the recognition sequence DEVD (5).
Function: Involved in the activation cascade of caspases responsible for apoptosis execution. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-:-Gly-217' bond. Overexpression promotes programmed cell death.
Subunit Structure: Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (p20) and a 11 kDa (p11) subunit. Interacts with BIRC6/bruce.
Post-translational Modifications: Cleavages by granzyme B or caspase-10 generate the two active subunits. Propeptide domains can also be cleaved efficiently by caspase-3. Active heterodimers between the small subunit of caspase-7 and the large subunit of caspase-3, and vice versa, also occur.
Similarity: Belongs to the peptidase C14A family
