Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables cysteine-type endopeptidase activator activity involved in apoptotic process; cysteine-type endopeptidase activity; and serine-type endopeptidase activity. Involved in several processes, including dichotomous subdivision of terminal units involved in lung branching; protein destabilization; and proteolysis. Acts upstream of or within apoptotic process and positive regulation of apoptotic signaling pathway. Predicted to be located in several cellular components, including cytoplasmic ribonucleoprotein granule; cytoskeleton; and secretory granule. Predicted to be active in extracellular space and lysosome. Is expressed in several structures, including brain; egg cylinder; genitourinary system; gut gland; and lung. Orthologous to human CTSH (cathepsin H).
