Background

Various biochemical, physiological and behavioural processes display circadian rhythms controlled by an internal biological clock. The central "gears" driving this clock appear to be composed of an autoregulatory transcription/posttranslation-based feedback loop. Cryptochrome 1 (CRY1) and 2 (CRY2) are DNA-binding flavoproteins that bear some homology to blue-light receptors and photolyases. In Drosophila, CRY is a photoreceptor for the circadian clock where it binds to the clock component TIM in a light-dependent fashion and blocks its function. Mammalian Cryptochrome 1 and Cryptochrome 2 function via light-independent interactions with circadian genes CLOCK and BMAL1, as well as with PER1, PER2, and TIM. They seem to act as light-independent components of the circadian clock and probably regulate Per1 transcriptional cycling via interactions with both the activator and its feedback inhibitors. Mutant mice not expressing the Cryptochrome 1 or Cryptochrome 2 protein display accelerated and delayed periodicity of locomotor activity, respectively. It appears that the combination of both proteins working together is essential to synchronize the organism to circadian phases. A critical balance between Cryptochrome 1 and Cryptochrome 2 is required for proper clock function; in complete darkness, double-mutant mice present with instantaneous arrhythmicity, indicating the absence of an internal circadian clock. Cryptochromes (Cry 1 and 2) are blue, ultraviolet-A photoreceptor pigment proteins that are involved circadian rhythm regulation in plants and animals. In mammals, Cry 1 and 2 expression oscillates with respect to the daily light-dark cycle in the suprachiasmatic nucleus of the hypothalamus. These proteins localize to the cell nucleus, interact with each of the Per proteins, and assist in the translocation of Per from the cytoplasm to nucleus.
