Comments
  • FUNCTION: Blue light-dependent regulator of the circadian feedback loop. Inhibits CLOCK|NPAS2-ARNTL E box-mediated transcription. Acts, in conjunction with CRY2, in maintaining period length and circadian rhythmicity. Has no photolyase activity. Capable of translocating circadian clock core proteins such as PER proteins to the nucleus. May inhibit CLOCK|NPAS2-ARNTL transcriptional activity through stabilizing the unphosphorylated form of ARNTL.
  • COFACTOR: Binds 1 FAD per subunit (By similarity).
  • COFACTOR: Binds 1 5,10-methenyltetrahydrofolate non-covalently per subunit (By similarity).
  • SUBUNIT: Component of the circadian core oscillator, which includes the CRY proteins, CLOCK or NPAS2, ARNTL or ARNTL2, 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 (By similarity).
  • SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Translocated to the nucleus through interaction with other Clock proteins such as PER2 or ARNTL.
  • TISSUE SPECIFICITY: Expressed in all tissues examined including fetal brain, fibroblasts, heart, brain, placenta, lung, liver, sketal muscle, kidney, pancreas, spleen, thymus, prostate, testis, ovary, small intestine, colon and leukocytes. Highest levels in heart and skeletal muscle.
  • PTM: Phosphorylation on Ser-266 by MAPK is important for the inhibition of CLOCK-ARNTL-mediated transcriptional activity. Phosphorylation by CSKNE requires interaction with PER1 or PER2.
  • SIMILARITY: Belongs to the DNA photolyase class-1 family.
  • SIMILARITY: Contains 1 DNA photolyase domain.
  • WEB RESOURCE: Name=Wikipedia; Note=Cryptochrome entry; URL="http://en.wikipedia.org/wiki/Cryptochrome";.
