General annotation (Comments)

Function	Serine protease that shows proteolytic activity against a non-specific substrate beta-casein. Promotes or induces cell death either by direct binding to and inhibition of BIRC proteins (also called inhibitor of apoptosis proteins, IAPs), leading to an increase in caspase activity, or by a BIRC inhibition-independent, caspase-independent and serine protease activity-dependent mechanism. Cleaves THAP5 and promotes its degradation during apoptosis. Isoform 2 seems to be proteolytically inactive. Ref.8 Ref.9
Catalytic activity	Cleavage of non-polar aliphatic amino acids at the P1 position, with a preference for Val, Ile and Met. At the P2 and P3 positions, Arg is selected most strongly with a secondary preference for other hydrophilic residues.
Subunit structure	Homotrimer. Interacts with MXI2. Interacts with THAP5 under apoptotic conditions. The mature protein, but not the precursor, binds to BIRC2/c-IAP1, BIRC3/c-IAP2 and XIAP/BIRC4. Interacts with BIRC6/bruce. Ref.6 Ref.8 Ref.9 Ref.11
Subcellular location	Mitochondrion intermembrane space. Mitochondrion membrane; Single-pass membrane protein Potential. Note: Predominantly present in the intermembrane space. Released into the cytosol following apoptotic stimuli, such as UV treatment, and stimulation of mitochondria with caspase-8 truncated BID/tBID.
Tissue specificity	Isoform 1 is ubiquitous. Isoform 2 is expressed predominantly in the kidney, colon and thyroid.
Domain	The mature N-terminus is involved in the interaction with XIAP. The PDZ domain mediates interaction with MXI2.
Post-translational modification	Autoproteolytically activated.
Involvement in disease	Parkinson disease 13 (PARK13) [MIM:610297]: A complex neurodegenerative disorder characterized by bradykinesia, resting tremor, muscular rigidity and postural instability, as well as by a clinically significant response to treatment with levodopa. The pathology involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.12 Ref.13
Sequence similarities	Belongs to the peptidase S1B family. Contains 1 PDZ (DHR) domain.
