Cytochrome P450 26A1 (CYP26A1)

Plays a key role in retinoic acid metabolism. Acts on retinoids, including all-trans-retinoic acid (RA) and its stereoisomer 9-cis-RA.

Capable of both 4-hydroxylation and 18- hydroxylation. Responsible for generation of several hydroxylated forms of RA, such as 4-OH-RA, 4-oxo-RA and 18-OH-RA.
