Predicted to enable carnitine O-palmitoyltransferase activity. Acts upstream of or within regulation of fatty acid beta-oxidation. Predicted to be located in membrane. Predicted to be active in mitochondrion. Is expressed in cardiac ventricle and liver. Human ortholog(s) of this gene implicated in carnitine palmitoyltransferase I deficiency and lipid metabolism disorder. Orthologous to human CPT1A (carnitine palmitoyltransferase 1A).
