Enables arginase activity; identical protein binding activity; and manganese ion binding activity. Involved in several processes, including cellular response to hormone stimulus; gland development; and response to vitamin. Located in several cellular components, including extracellular space; mitochondrial outer membrane; and neuronal cell body. Used to study acute necrotizing pancreatitis and hypertension. Biomarker of several diseases, including acute kidney failure; cholestasis; silicosis; ureteral obstruction; and uveitis. Human ortholog(s) of this gene implicated in asthma; hepatocellular carcinoma; and hyperargininemia. Orthologous to human ARG1 (arginase 1). [provided by Alliance of Genome Resources, Apr 2022]
