Abstract excerpt
Phosphorylation plays a key role in the precise timing of circadian clocks. Daily rhythms of phosphorylation of the Drosophila circadian clock component PERIOD (PER) were first described more than a decade ago, yet little is known about their phosphorylation sites and their function in circadian behavior. Here we show that serines 151 and 153 in PER are required for robust in vitro phosphorylation by the casein...
