The circadian clock facilitates a temporal coordination of most homeostatic activities and their synchronization with the environmental cycles of day and night. The core oscillating activity of the circadian clock is formed by a heterodimer of the transcription factors CLOCK (CLK) and CYCLE (CYC). Post-translational regulation of CLK/CYC has previously been(More)
Phosphorylation is a pivotal regulatory mechanism for protein stability and activity in circadian clocks regardless of their evolutionary origin. It determines the speed and strength of molecular oscillations by acting on transcriptional activators and their repressors, which form negative feedback loops. In Drosophila, the CK2 kinase phosphorylates and(More)
Circadian clocks allow a temporal coordination and segregation of physiological, metabolic, and behavioural processes as well as their synchronization with the environmental cycles of day and night. Circadian regulation thereby provides a vital advantage, improving an organisms' adaptation to its environment. The molecular clock can be synchronized with(More)
