Subcellular location [CC][Isoform 1]: Nucleus {ECO:0000269|PubMed:22274616}. Cytoplasm {ECO:0000250|UniProtKB:O54943}. Cytoplasm, perinuclear region {ECO:0000250|UniProtKB:O54943}. Note=Nucleocytoplasmic shuttling is effected by interaction with other circadian core oscillator proteins and/or by phosphorylation. Translocate to the nucleus after phosphorylation by CSNK1D or CSNK1E. Also translocated to the nucleus by CRY1 or CRY2. PML regulates its nuclear localization. {ECO:0000250|UniProtKB:O54943}.;
[Isoform 2]: Nucleus, nucleolus {ECO:0000269|PubMed:24202686}.
