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 Per1 and Per2, two regulators of the circadian clock that display tumor suppressor activity. HEK293T cells were transfected with Cry2, Skp1, Cul1, and Roc1 in the absence or presence of either FLAG-tagged Fbxl3 or a FLAG-tagged Fbxl3(ΔF-box) mutant. Fbxl3, but not an inactive Fbxl3(ΔF-box) mutant (4), induced the ubiquitination of Cry2 (Fig. 2D), which supports the notion that the effect of Fbxl3 on Cry2 is direct. |
