Functioni

Transcriptional repressor which forms a core component of the circadian clock. The circadian clock, an internal time-keeping system, regulates various physiological processes through the generation of approximately 24 hour circadian rhythms in gene expression, which are translated into rhythms in metabolism and behavior. It is derived from the Latin roots 'circa' (about) and 'diem' (day) and acts as an important regulator of a wide array of physiological functions including metabolism, sleep, body temperature, blood pressure, endocrine, immune, cardiovascular, and renal function. Consists of two major components: the central clock, residing in the suprachiasmatic nucleus (SCN) of the brain, and the peripheral clocks that are present in nearly every tissue and organ system. Both the central and peripheral clocks can be reset by environmental cues, also known as Zeitgebers (German for 'timegivers'). The predominant Zeitgeber for the central clock is light, which is sensed by retina and signals directly to the SCN. The central clock entrains the peripheral clocks through neuronal and hormonal signals, body temperature and feeding-related cues, aligning all clocks with the external light/dark cycle. Circadian rhythms allow an organism to achieve temporal homeostasis with its environment at the molecular level by regulating gene expression to create a peak of protein expression once every 24 hours to control when a particular physiological process is most active with respect to the solar day. Transcription and translation of core clock components (CLOCK, NPAS2, ARNTL/BMAL1, ARNTL2/BMAL2, PER1, PER2, PER3, CRY1 and CRY2) plays a critical role in rhythm generation, whereas delays imposed by post-translational modifications (PTMs) are important for determining the period (tau) of the rhythms (tau refers to the period of a rhythm and is the length, in time, of one complete cycle). A diurnal rhythm is synchronized with the day/night cycle, while the ultradian and infradian rhythms have a period shorter and longer than 24 hours, respectively. Disruptions in the circadian rhythms contribute to the pathology of cardiovascular diseases, cancer, metabolic syndromes and aging. A transcription/translation feedback loop (TTFL) forms the core of the molecular circadian clock mechanism. Transcription factors, CLOCK or NPAS2 and ARNTL/BMAL1 or ARNTL2/BMAL2, form the positive limb of the feedback loop, act in the form of a heterodimer and activate the transcription of core clock genes and clock-controlled genes (involved in key metabolic processes), harboring E-box elements (5'-CACGTG-3') within their promoters. The core clock genes: PER1/2/3 and CRY1/2 which are transcriptional repressors form the negative limb of the feedback loop and interact with the CLOCK|NPAS2-ARNTL/BMAL1|ARNTL2/BMAL2 heterodimer inhibiting its activity and thereby negatively regulating their own expression. This heterodimer also activates nuclear receptors NR1D1/2 and RORA/B/G, which form a second feedback loop and which activate and repress ARNTL/BMAL1 transcription, respectively. CRY1 and CRY2 have redundant functions but also differential and selective contributions at least in defining the pace of the SCN circadian clock and its circadian transcriptional outputs. Less potent transcriptional repressor in cerebellum and liver than CRY1, though less effective in lengthening the period of the SCN oscillator. Seems to play a critical role in tuning SCN circadian period by opposing the action of CRY1. With CRY1, dispensable for circadian rhythm generation but necessary for the development of intercellular networks for rhythm synchrony. May mediate circadian regulation of cAMP signaling and gluconeogenesis by blocking glucagon-mediated increases in intracellular cAMP concentrations and in CREB1 phosphorylation. Besides its role in the maintenance of the circadian clock, is also involved in the regulation of other processes. Plays a key role in glucose and lipid metabolism modulation, in part, through the transcriptional regulation of genes involved in these pathways, such as LEP or ACSL4. Represses glucocorticoid receptor NR3C1/GR-induced transcriptional activity by binding to glucocorticoid response elements (GREs). Represses the CLOCK-ARNTL/BMAL1 induced transcription of BHLHE40/DEC1 and NAMPT.10 Publications

Cofactori

Protein has several cofactor binding sites:
  • FAD1 PublicationNote: Binds 1 FAD per subunit. Only a minority of the protein molecules contain bound FAD. Contrary to the situation in photolyases, the FAD is bound in a shallow, surface-exposed pocket.1 Publication
  • 5,10-methylenetetrahydrofolateBy similarityNote: Binds 1 5,10-methenyltetrahydrofolate non-covalently per subunit.By similarity

Enzyme regulationi

KL001 (N-[3-(9H-carbazol-9-yl)-2-hydroxypropyl]-N-(2-furanylmethyl)-methanesulfonamide) binds to CRY1 and stabilizes it by inhibiting FBXL3- and ubiquitin-dependent degradation of CRY1 resulting in lengthening of the circadian periods. KL001-mediated CRY1 stabilization can inhibit glucagon-induced gluconeogenesis in primary hepatocytes.1 Publication

Disruption phenotypei

Animals show longer circadian periods. Double knockouts of CRY1 and CRY2 show slightly decrease body weight and lose the cycling rhythmicity of feeding behavior, energy expenditure and glucocorticorids expression. Glucose homeostasis is severely disrupted and animals exhibit elevated blood glucose in response to acute feeding after an overnight fast as well as severely impaired glucose clearance in a glucose tolerance test. When challenged with high-fat diet, animals rapidly gain weight and surpass that of wild-type mice, despite displaying hypophagia. They exhibit hyperinsulinemia and selective insulin resistance in the liver and muscle but show high insulin sensitivity in adipose tissue and consequent increased lipid uptake. Mice display enlarged gonadal, subcutaneous and perirenal fat deposits with adipocyte hypertrophy and increased lipied accumulation in liver.4 Publications

Post-translational modificationi

Phosphorylation on Ser-265 by MAPK is important for the inhibition of CLOCK-ARNTL-mediated transcriptional activity. Phosphorylation by CSKNE requires interaction with PER1 or PER2. Phosphorylated in a circadian manner at Ser-553 and Ser-557 in the suprachiasmatic nucleus (SCN) and liver. Phosphorylation at Ser-557 by DYRK1A promotes subsequent phosphorylation at Ser-553 by GSK3-beta: the two-step phosphorylation at the neighboring Ser residues leads to its proteasomal degradation.4 Publications
Ubiquitinated by the SCF(FBXL3) and SCF(FBXL21) complexes, regulating the balance between degradation and stabilization. The SCF(FBXL3) complex is mainly nuclear and mediates ubiquitination and subsequent degradation of CRY2. In contrast, cytoplasmic SCF(FBXL21) complex-mediated ubiquitination leads to stabilize CRY2 and counteract the activity of the SCF(FBXL3) complex. The SCF(FBXL3) and SCF(FBXL21) complexes probably mediate ubiquitination at different Lys residues. The SCF(FBXL3) complex recognizes and binds CRY2 phosphorylated at Ser-553 and Ser-557. Ubiquitination may be inhibited by PER2.6 Publications

Component of the circadian core oscillator, which includes the CRY proteins, CLOCK or NPAS2, ARNTL/BMAL1 or ARNTL2/BMAL2, CSNK1D and/or CSNK1E, TIMELESS, and the PER proteins. Interacts directly with PER1 and PER2 C-terminal domains. Interaction with PER2 inhibits its ubiquitination and vice versa. Interacts with NFIL3. Interacts with FBXL3 and FBXL21. FBXL3, PER2 and the cofactor FAD compete for overlapping binding sites. FBXL3 cannot bind CRY2 that interacts already with PER2 or that contains bound FAD. Interacts with PPP5C (via TPR repeats); the interaction downregulates the PPP5C phosphatase activity on CSNK1E. AR, NR1D1, NR3C1/GR, RORA and RORC; the interaction, at least, with NR3C1/GR is ligand dependent. Interacts with PRKDC and CIART.17 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
