The daf-9 gene encodes a cytochrome p450 enzyme that catalyses the generation of dafachronic acid (a steroid hormone) in the worm Caenorhabditis elegans,[1][2] with the CYP Symbol CYP22A1 (Cytochrome P450, family 22, member A1). After generation, dafachronic acid will bind its nuclear receptor Daf-12, whose genetic mutation has been implicated by Cynthia Kenyon and colleagues as related to the formation of Dauer larva.[3]
