Predicted to enable serine-type endopeptidase activity. Predicted to be involved in several processes, including insulin catabolic process; regulation of insulin secretion; and regulation of platelet aggregation. Predicted to act upstream of or within establishment of skin barrier. Predicted to be located in extracellular region and keratohyalin granule. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in abdominal obesity-metabolic syndrome 4. Orthologous to several human genes including CELA2A (chymotrypsin like elastase 2A).
