Predicted to enable cysteine-type endopeptidase activity. Predicted to be involved in immune response and proteolysis involved in cellular protein catabolic process. Predicted to be located in several cellular components, including Golgi apparatus; endosome; and perinuclear region of cytoplasm. Predicted to be active in extracellular space and lysosome. Human ortholog(s) of this gene implicated in hypertrophic cardiomyopathy. Orthologous to human CTSL (cathepsin L). [provided by Alliance of Genome Resources, Apr 2022]
