Abstract:
One component of the circadian clock in mammals is the Clock-Bmal1 heterodimeric transcription factor. Among its downstream targets, two genes, Cry1 and Cry2, encode inhibitors of the Clock-Bmal1 complex that establish a negative-feedback loop. We found that both Cry1 and Cry2 proteins are ubiquitinated and degraded via the SCF(Fbxl3) ubiquitin ligase complex. This regulation by SCF(Fbxl3) is a prerequisite for the efficient and timely reactivation of Clock-Bmal1 and the consequent expression of...     »
