Webfeedback circuit where core transcriptional activators (Clock and Bmal1) drive the expression of their own negative regulators (Cry1-2, Per1-3) [4, 5]. This attribute of the clock results in a negative transcriptional and translational feedback loop encoded by several genes that perpetuates oscillations in gene expression that occur every 24 hrs. WebAug 20, 2024 · BMAL1 is the core orchestrator of the molecular clock, and the only single clock gene deletion that leads to complete ablation of all rhythms. BMAL1 forms a heterodimeric partnership with CLOCK and binds to E-box sites located across the genome, inducing rhythmic expression in clock-controlled genes ( 1 ).
WebBy using an RNA- and ChIP-seq genome-wide approaches we identified that BMAL1 binds the promoters of CCNA1 and CDK1 genes and controls their expression in EC. …
