CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in the metabolism of
CC all-trans retinoic acid (atRA), a signaling molecule that binds to
CC retinoic acid receptors and regulates gene transcription.
CC Mechanistically, uses molecular oxygen inserting one oxygen atom into a
CC substrate, and reducing the second into a water molecule, with two
CC electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-
CC ferrihemoprotein reductase). Catalyzes the hydroxylation of carbon
CC hydrogen bonds of atRA primarily at C-4 and C-18. Has no activity
CC toward 9-cis and 13-cis retinoic acid stereoisomers (PubMed:22020119,
CC PubMed:9228017, PubMed:9716180). May play a role in the oxidative
CC metabolism of xenobiotics such as tazarotenic acid (PubMed:26937021).
