WebSep 9, 2015 · Cryptochrome (CRY) is one of the key elements of the circadian system in animals. In plants, CRY acts as a blue light receptor to entrain circadian rhythms, and mediates a variety of light responses, such as the regulation of flowering and seedling growth. Results We performed a comprehensive evolutionary analysis of the CRY/PHR … WebHuman CRY1 variants associate with attention deficit/hyperactivity disorder. The circadian cryptochrome, CRY1, is a pro-tumorigenic factor that rhythmically modulates DNA repair. The human CRY1 tail controls circadian timing by regulating its association with CLOCK:BMAL1.
