The DAF-12 (abnormal dauer formation protein 12) gene encodes the nuclear receptor of dafachronic acid (a steroid hormone) in the worm Caenorhabditis elegans , with the NRNC Symbol NR1J1 as the homolog of nuclear hormone receptor HR96 (Hr96) in Drosophila melanogaster. [1] DAF-12 has been implicated by Cynthia Kenyon and colleagues in the formation of Dauer larva. [2]
In favorable environments, a cytochrome p450 Daf-9 (Cyp22a1) [3] produce dafachronic acid to binding Daf-12 to initiating downstream gene expression. [4] When in unfavorable environments, like starvation, dafachronic acid decreases, Daf-12 will form a complex with co-repressor DIN-1. [5]
