CC -!- FUNCTION: Serine protease that shows proteolytic activity against a
CC non-specific substrate beta-casein. Promotes or induces cell death
CC either by direct binding to and inhibition of BIRC proteins (also
CC called inhibitor of apoptosis proteins, IAPs), leading to an increase
CC in caspase activity, or by a BIRC inhibition-independent, caspase-
CC independent and serine protease activity-dependent mechanism. Can
CC antagonize antiapoptotic activity of th by directly inducing the
CC degradation of th (By similarity). {ECO:0000250|UniProtKB:Q9VFJ3}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Cleavage of non-polar aliphatic amino-acids at the P1
CC position, with a preference for Val, Ile and Met. At the P2 and P3
CC positions, Arg is selected most strongly with a secondary preference
CC for other hydrophilic residues.; EC=3.4.21.108;
CC -!- SUBUNIT: Interacts with th/DIAP1 (via BIR 2 domain).
CC {ECO:0000250|UniProtKB:Q9VFJ3}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion intermembrane space
CC {ECO:0000250|UniProtKB:Q9VFJ3}; Single-pass membrane protein
CC {ECO:0000255}. Mitochondrion membrane {ECO:0000250|UniProtKB:Q9VFJ3};
CC Single-pass membrane protein {ECO:0000255}. Note=Predominantly present
CC in the intermembrane space. Released into the cytosol following
CC apoptotic stimuli, such as UV treatment. The extramitochondrial protein
CC does not diffuse throughout the cytosol but stays near the
CC mitochondria. {ECO:0000250|UniProtKB:Q9VFJ3}.
CC -!- SIMILARITY: Belongs to the peptidase S1C family. {ECO:0000255}.
