Abstract: Circadian clocks evolved to coordinate behavior and physiology to our 24 h environment.  By measuring photoperiod (day length), circadian clocks can also mediate adaptive responses to different seasons.  Yet the molecular mechanisms  by which this works remains unclear.  Here we describe a novel clock component important for mediating the appropriate behavioral response to changing photoperiod.  Disrupted clocks are also a common element of neurodegenerative diseases and may contribute to their pathology.  Using a Huntington’s model, we demonstrate that the circadian clock can play a causal role in this disease and we apply genetic screening to discover novel pathways that link the clock to neurodegeneration.
