Abstract

Cellular circadian clocks, the molecular timers that coordinate physiology to the day/night cycle across the domains of life, are widely regulated by disordereddisordered protein interactions. Here, we review the disordered-disordered protein interactions in the circadian clock of Neurospora crassa (N. crassa), a filamentous fungus which is a model organism for clocks in higher eukaryotes. We focus on what is known about the interactions between the intrinsically disordered core negative arm protein FREQUENCEY (FRQ), the other proteins comprising the transcription-translation feedback loop, and the proteins that control output. We compare and contrast this model with other models of eukaryotic clocks, illustrating that protein disorder is a conserved and essential mechanism in the maintenance of circadian clock across species.
