Nardilysin fine-tunes the mammalian circadian clock through selective modulation of PER2 function
Circadian rhythms in mammals are generated by negative feedback loops, in which CLOCK and BMAL1 bind to E-box to activate transcription of Period (Per) and Cryptochrome (Cry) and the E-box-dependent transactivation is inhibited by PER and CRY proteins. Although the core transcriptional feedback loop of the circadian cl...
