Webidentified a CLOCK-binding small molecule (CLK8) that decreased the interaction between CLOCK and BMAL1 inter-fering in the translocation of CLOCK into the nucleus both in vivo and in vitro. Our results show that a decrease in nuclear CLOCK leads to the stabilization of the negative arm of the TTFL and, in turn, enhances the amplitude of the ... WebThe secondary TTFL, which drives the cyclic transcription of Bmal1 and Clock, is composed of members of the orphan nuclear receptor families REV-ERB (REV-ERBα,β) and ROR (RORα,β,γ). The cyclic expression of REV-ERBs is governed by the primary TTFL, and the two TTFLs are thus tightly coupled.
