Involvement of the protein kinase CK2 in the regulation of mammalian circadian rhythms.

Abstract excerpt

Posttranslational modifications of clock proteins are crucial to generating proper circadian rhythms of the correct length and amplitude. Here, we show that the protein kinase CK2 (casein kinase 2) plays a role in regulating the mammalian circadian clock. We found that inhibiting CK2 activity resulted in a decrease in the amplitude and an increase in the period of oscillations in circadian gene expression. CK2...
