Halloween genes encode P450 enzymes that mediate steroid hormone biosynthesis in Drosophila melanogaster.
Gilbert LI. Gilbert LI. Mol Cell Endocrinol. 2004 Feb 27;215(1-2):1-10. doi: 10.1016/j.mce.2003.11.003. Mol Cell Endocrinol. 2004. PMID: 15026169 Review.
Mutation of members of the Halloween gene family results in embryonic lethality. We have shown that two of these genes code for enzymes responsible for specific steps in the synthesis of ecdysone, a polyhydroxylated sterol that is the precursor of the major m …
