WebMay 11, 2024 · Abstract Cryptochromes (CRYs) are blue-light receptors in plants that harbor FAD as a cofactor and regulate various physiological responses. Photoactivated CRYs undergo oligomerization, which... WebA pathogenic variant in cryptochrome 1 (CRY1) leads to DSPD. CRY1 encodes a protein that is a core component of the molecular clock to regulate the timing of circadian rhythms. Genetic testing was obtained in a family with multiple members with DSPD, revealing a CRY1 pathogenic variant (c.1657+3A>C).

WebDec 27, 2010 · Cryptochrome (CRY) is a flavoprotein that regulates growth and development in plants in response to blue light, functions as a circadian photoreceptor in Drosophila and other insects, and acts as a core component of the molecular clock in mammalian organisms (1–4).Despite extensive research on CRYs photosensory function … WebCPF protein family performs wide range of functions depending on the type of organism. For example, photolyases repair UV-induced DNA damages while cryptochromes act as a transcriptional repressors of the circadian clock in mammals ( Sancar, 2000 ).
