Description

Predicted to have cysteine-type endopeptidase activity. Predicted to be involved in proteolysis involved in cellular protein catabolic process. Localizes to extracellular region. Human ortholog(s) of this gene implicated in hypertrophic cardiomyopathy. Is expressed in several structures, including ectoderm; hatching gland; hatching gland cell; hypoblast; and mesoderm. Orthologous to several human genes including CTSL (cathepsin L).
