Rhythmic gene expression

Caption

The circadian clock controls the rhythmic expression of hundreds of genes in the cyanobacterium Synechococcus elongatus. The pacemaker of the clock is a core oscillator made up of three proteins: KaiA, KaiB and KaiC. Temporal information is relayed to a transcription factor, RpaA, via two kinases, CikA and SasA, that physically interact with the Kai complex.
