title: Posttranslational control of the Neurospora circadian clock.
abstract: The eukaryotic circadian clocks are composed of autoregulatory circadian negative feedback loops that include both positive and negative elements. Investigations of the Neurospora circadian clock system have elucidated many of the basic mechanisms that underlie circadian rhythms, including negative feedback and light and temperature entrainment common to all eukaryotic clocks. The conservation of the posttranslational regulators in divergent circadian systems suggests that the processes mediating the modification and degradation of clock proteins may be the common foundation that allows the evolution of circadian clocks in eukaryotic systems. In this chapter, we summarize recent studies of the Neurospora circadian clock with emphasis on posttranslational regulation in the circadian negative feedback loop.
