Enables serine-type endopeptidase activity. Involved in several processes, including peptide hormone processing; regulation of renal sodium excretion; and regulation of systemic arterial blood pressure by atrial natriuretic peptide. Located in cell surface. Is expressed in several structures, including floor plate; heart; lip; phalanx; and skin. Human ortholog(s) of this gene implicated in hypertension and pre-eclampsia. Orthologous to human CORIN (corin, serine peptidase). [provided by Alliance of Genome Resources, Apr 2022]
