New pathway to understanding circadian rhythms
The mechanism that keeps track of time in our body is based on a perpetual secretion of clock proteins in a 24-hour feedback loop. But the signaling molecules that control this clock are largely unknown. In September 21 Science Julie Williams and colleagues from Howard Hughes Medical Institute, show that that the protein produced by Drosophila version of the neurofibromatosis-1 (Nf1) gene controls the circadian machinery via the Ras/MAPK signaling pathway.Williams et al. studied Drosophila with
