Circadian clocks regulate daily fluctuations of many physiological and behavioral aspects in life. They are synchronized with the environment via light or temperature cycles [1]. Natural fluctuations of the day length (photoperiod) and temperature necessitate a daily reset of the circadian clock on the molecular level. In Drosophila, the blue-light(More)
Circadian clock function depends on the tightly regulated exclusion or presence of clock proteins within the nucleus. A newly induced long-period timeless mutant, tim(blind), encodes a constitutively hypophosphorylated TIM protein. The mutant protein is not properly degraded by light, and tim(blind) flies show abnormal behavioral responses to light pulses.(More)
