General annotation (Comments)

Function	Component of the circadian clock mechanism which is essential for generating circadian rhythms. Function unknown.
Subunit structure	Homodimer. Component of the circadian core oscillator, which includes the CRY proteins, CLOCK or NPAS2, BMAL1 or BMAL2, CSNK1D and/or CSNK1E, TIMELESS and the PER proteins. Interacts directly with PER1, PER2, CRY1, CRY2, and TIMELESS. Interaction with CSNK1D or CSKN1E promotes nuclear location of PER proteins By similarity.
Subcellular location	CytoplasmBy similarity. NucleusBy similarity. Note= Mainly cytoplasmic. Translocates to the nucleus through binding PER1, PER2, CRY1 or CRY2, but not TIMELESS By similarity.
Post-translational modification	Phosphorylation appears to require association with PER1 and translocation to the nucleus By similarity. Ubiquitinated By similarity.
Sequence similarities	Contains 1 PAC (PAS-associated C-terminal) domain. Contains 2 PAS (PER-ARNT-SIM) domains.
