CC   -!- FUNCTION: Blue light-dependent regulator of the circadian feedback
CC       loop. Inhibits CLOCK|NPAS2-ARNTL E box-mediated transcription.
CC       Acts, in conjunction with CRY2, in maintaining period length and
CC       circadian rhythmicity. Has no photolyase activity. Capable of
CC       translocating circadian clock core proteins such as PER proteins
CC       to the nucleus. May inhibit CLOCK|NPAS2-ARNTL transcriptional
CC       activity through stabilizing the unphosphorylated form of ARNTL.
CC   -!- COFACTOR: Binds 1 FAD per subunit (By similarity).
CC   -!- COFACTOR: Binds 1 5,10-methenyltetrahydrofolate non-covalently per
CC       subunit (By similarity).
CC   -!- SUBUNIT: Component of the circadian core oscillator, which
CC       includes the CRY proteins, CLOCK or NPAS2, ARNTL or ARNTL2, CSNK1D
CC       and/or CSNK1E, TIMELESS, and the PER proteins. Interacts directly
CC       with PER1 and PER2 C-terminal domains. Interaction with PER2
CC       inhibits its ubiquitination and vice versa. Interacts with NFIL3
CC       (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Translocated to the
CC       nucleus through interaction with other Clock proteins such as PER2
CC       or ARNTL.
CC   -!- TISSUE SPECIFICITY: Expressed in all tissues examined including
CC       fetal brain, fibroblasts, heart, brain, placenta, lung, liver,
CC       sketal muscle, kidney, pancreas, spleen, thymus, prostate, testis,
CC       ovary, small intestine, colon and leukocytes. Highest levels in
CC       heart and skeletal muscle.
CC   -!- PTM: Phosphorylation on Ser-266 by MAPK is important for the
CC       inhibition of CLOCK-ARNTL-mediated transcriptional activity.
CC       Phosphorylation by CSKNE requires interaction with PER1 or PER2.
CC   -!- SIMILARITY: Belongs to the DNA photolyase class-1 family.
CC   -!- SIMILARITY: Contains 1 DNA photolyase domain.
