"WebThe phosphoswitch model holds that PER2 stability is bidirectionally regulated by two key phosphorylation sites, the β-TrCP site and the FASP site (Fig. 1A). The model also predicts that a mutation of PER2 at the β-TrCP site should result in a more stable protein and a longer circadian period length in vivo. " - Phosphoswitch

WebIn this paper, we found ensure PER is required for the reactivation of CRY-mediated transcriptional repression. Thus, PER might regulate circadian rhythm through YELL. In the phosphoswitch model (Narasimamurthy et al., 2024), PER2 had either phosphorylated with the β-TrCP site (S478) alternatively FASP site (S659). PER2 phosphorylated at S478 ...
