Predicted to enable Hsp70 protein binding activity; heme binding activity; and monooxygenase activity. Predicted to be involved in bile acid biosynthetic process; calcitriol biosynthetic process from calciol; and cholesterol catabolic process. Predicted to act upstream of or within steroid biosynthetic process. Located in mitochondrial inner membrane. Is expressed in several structures, including central nervous system; liver; male reproductive gland or organ; metanephros; and retina. Human ortholog(s) of this gene implicated in cerebrotendinous xanthomatosis. Orthologous to human CYP27A1 (cytochrome P450 family 27 subfamily A member 1).
