WebMar 12, 2015 · Ras is a universal eukaryotic intracellular membrane-anchored 21-kDa protein, which belongs to the large family of small monomeric GTPases. It regulates distinct signal transduction pathways that play an important role in the proper functioning of neurons, where it mediates versatile cellular responses to extracellular cues [1, 2]. WebIn vivo, violet light administered to mice at circadian time (CT) 13 elicited strong induction of Per1 and Per2 transcripts, which was abrogated in Opn5 −/− mice (Figure 3B). These results suggest photic induction of Per1 and Per2 in skin is gated by the circadian clock as has been described in the SCN
