. "SEQUENCE 303 AA; 34277 MW; CD373EE54A232CA4 CRC64;"^^ . "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. CATALYTIC ACTIVITY: Strict requirement for an Asp residue at position P1 and has a preferred cleavage sequence of Asp-Glu-Val- Asp-|-. ENZYME REGULATION: Inhibited by isatin sulfonamides. SUBUNIT: 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. SUBCELLULAR LOCATION: Cytoplasm. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=3; Name=Alpha; IsoId=P55210-1; Sequence=Displayed; Name=Beta; IsoId=P55210-2; Sequence=VSP_000807; Note=Lacks enzymatic activity; Name=Alpha'; Synonyms=Beta; IsoId=P55210-3; Sequence=VSP_000806; Note=What we call isoform Alpha' is also known as Beta (PubMed:9070923); TISSUE SPECIFICITY: Highly expressed in lung, skeletal muscle, liver, kidney, spleen and heart, and moderately in testis. No expression in the brain. PTM: 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. GENE SYNONYMS:CASP7 MCH3.
