Proposed working model of the EC-JMJ29 complex in circadian control. Circadian expression of CCA1 and PRR9 are associated with H3K4me3 levels. SDG2 possibly catalyzes the H3K4me3 deposition at the CCA1 and PRR9 promoters at dawn, facilitating raising phase of gene expression. After peak expression, the declining phase of CCA1 and PRR9 is shaped by the Evening Complex (EC) and JMJ29. The EC recruits JMJ29 to the CCA1 and PRR9 promoters and removes H3K4me3 at dusk, maintaining low levels of expression during evening time.
