Phosphoswitch

WebOct 1, 2015 · The phosphoswitch provides a biochemical mechanism for circadian temperature compensation of circadian period. This phosphoswitch additionally explains … 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.
