Protein
Serine protease HTRA2, mitochondrial
Organism
Drosophila pseudoobscura pseudoobscura
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. Can antagonize antiapoptotic activity of th by directly inducing the degradation of th (By similarity).
Similarity
Belongs to the peptidase S1C family.
