Transcriptional autoregulation by phosphorylated and non-phosphorylated KaiC in cyanobacterial circadian rhythms.

Journal of theoretical biology - 21 Jul 2006

Takigawa-Imamura Hisako, Mochizuki Atsushi

Abstract excerpt

Cyanobacteria are the simplest organisms known to exhibit circadian rhythms, which is the fundamental process of homeostasis adapting to daily environmental changes. The cyanobacterial clock gene products, KaiA, KaiB, and KaiC interact with each other, and regulate KaiC phosphorylation and kaiBC expression in a circadian fashion. Molecular genetic study recently proposed that KaiC protein may enhance and repress...
