Enables several functions, including identical protein binding activity; ornithine carbamoyltransferase activity; and phosphate ion binding activity. Involved in several processes, including alpha-amino acid metabolic process; response to biotin; and urea cycle. Located in mitochondrial inner membrane. Used to study ornithine carbamoyltransferase deficiency. Biomarker of cholestasis; fatty liver disease; and obesity. Human ortholog(s) of this gene implicated in ornithine carbamoyltransferase deficiency. Orthologous to human OTC (ornithine transcarbamylase). [provided by Alliance of Genome Resources, Apr 2022]
