Circadian photoreception in Drosophila: functions of cryptochrome in peripheral and central clocks.

Abstract excerpt

In Drosophila melanogaster, disruption of night by even short light exposures results in degradation of the clock protein TIMELESS (TIM), leading to shifts in the fly molecular and behavioral rhythms. Several lines of evidence indicate that light entrainment of the brain clock involves the blue-light photoreceptor cryptochrome (CRY). In cryptochrome-depleted Drosophila (cry(b)), the entrainment of the brain clock...
