Predicted to enable serine-type endopeptidase activity. Acts upstream of or within several processes, including elastin catabolic process; pancreas development; and regulation of transcription by RNA polymerase II. Located in collagen-containing extracellular matrix. Is expressed in alveolus epithelium; lung; pancreas; pancreas tip epithelium; and right lung accessory lobe. Orthologous to human CELA1 (chymotrypsin like elastase 1). [provided by Alliance of Genome Resources, Apr 2022]
