Background

PER2 (period circadian protein homolog 2 or circadian clock protein PERIOD 2) is a component of the circadian clock mechanism which is essential for generating circadian rhythms and PER2 acts as a negative element in the circadian transcriptional loop. PER2 modulates the clock function by interacting with other circadian regulatory proteins for transporting them to nucleus, and negatively regulates CLOCK|NPAS2-BMAL1|BMAL2-induced transactivation. PER2 forms a component of the circadian core oscillator, which also includes the CRY proteins, CLOCK or NPAS2, BMAL1 or BMAL2, CSNK1D and/or CSNK1E, TIMELESS proteinsetc. PER2 interacts with NFIL3, PER1, PER3, CRY1 and CRY2 proteins, and its interaction with CSNK1D or CSNK1E promotes nuclear localization of PER proteins. PER2 is a nuclear protein and its nucleo-cytoplasmic shuttling is effected by interaction with other circadian core oscillator proteins and/or by phosphorylation. CSNK1E and CSNK1D facilitate PER2 phosphorylation that follows its degradation. PER2 defects have been found to be responsible for familial advanced sleep-phase syndrome (FASPS).
