  • Target

    • 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.
    • Tissue specificity

      Expressed in all tissues examined including fetal brain, fibroblasts, heart, brain, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, testis, ovary, small intestine, colon and leukocytes. Highest levels in heart and skeletal muscle.
    • Sequence similarities

      Belongs to the DNA photolyase class-1 family.
      Contains 1 DNA photolyase domain.
    • Post-translational

      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.
      Ubiquitinated by the SCF(FBXL3) and SCF(FBXL21) complex, leading to its degradation.
    • Cellular localization

      Cytoplasm. Nucleus. Translocated to the nucleus through interaction with other Clock proteins such as PER2 or ARNTL.
