The cellular stress response and circadian clock system are fundamental functions in homeostatic regulation in almost all organisms. However, whether these two mechanisms are interlocked with each other, and the key molecule that links cellular stress and the circadian clock, remain unclear. Here we identify ASK family kinases that are essential for the circadian clock to respond to cellular stress, and report that Ask1 transcription is rhythmically controlled by the circadian clock. Moreover, LC-MS/MS?based proteomic analysis provides insight into a molecular mechanism in which dephosphorylation-triggered changes to the ASK complex mediate cellular stress to the circadian clock. From the perspective of cell signaling, our present findings expand previously reported roles of stress signaling toward regulation of the circadian clock.
