CC -!- FUNCTION: Serves as the first electron transfer protein in all the
CC mitochondrial P450 systems including cholesterol side chain cleavage in
CC all steroidogenic tissues, steroid 11-beta hydroxylation in the adrenal
CC cortex, 25-OH-vitamin D3-24 hydroxylation in the kidney, and sterol C-
CC 27 hydroxylation in the liver. {ECO:0000256|ARBA:ARBA00003133}.
