Human casein kinase Idelta phosphorylation of human circadian clock proteins period 1 and 2. We have now extended our previous studies to show that human casein kinase Idelta (hCKIdelta), the closest homologue to hCKIepsilon, associates with and phosphorylates hPER1 and causes protein instability. Furthermore, we observed that both hCKIdelta and hCKIepsilon phosphorylated and caused protein instability of human period 2 protein (hPER2). |

AMPK enhances mPer2 degradation and CKIɛ activity by phosphorylating Ser-389 of CKIɛ. One of the regulators of the period length is casein kinase Iepsilon (CKIepsilon), which by phosphorylating and inducing the degradation of the circadian clock component, mPer2, shortens the period length. AMPK phosphorylates Ser-389 of CKIepsilon, resulting in increased CKIepsilon activity and degradation of mPer2. |

The mammalian circadian regulatory proteins PER1 and PER2 undergo a daily cycle of accumulation followed by phosphorylation and degradation. CKIepsilon-mediated phosphorylation of PER2 recruits the ubiquitin ligase adapter protein beta-TrCP to a specific site, and dominant negative beta-TrCP blocks phosphorylation-dependent degradation of mPER2. These results provide a biochemical mechanism and functional relevance for the observed phosphorylation-degradation cycle of mammalian PER2. |

Here, the authors show that the F-box protein beta-transducin repeat containing protein 1 (beta-TrCP1) as part of the E3 ubiquitin ligase complex is an essential component of the mammalian circadian oscillator. Down-regulation of endogenous beta-TrCP1 as well as expression of a dominant-negative form both result in lengthening of the circadian period in oscillating fibroblasts. These phenotypes are due to an impaired degradation of PERIOD (PER) proteins, since expression of beta-TrCP interaction-deficient PER2 variants--but not wild-type PER2--results in a dramatic stabilization of PER2 protein as well as in the disruption of circadian rhythmicity. |

BMAL1/clock (or NPAS2) heterodimers activate the expression of the period (PER) and cryptochrome (CRY) genes acting as transcription factors directed to the PER and CRY promoters via E-box elements. PER and CRY proteins form heterodimers and suppress the activity of the BMAL1/clock (or NPAS2) completing the feedback loop. |
