Atomic structure of essential circadian clock protein complex determined

For the first time, the molecular structure of a protein complex that plays an important role in regulating the circadian rhythm has been identified by a team of researchers. "Our circadian clock controls many important physiological functions," explained one resesarcher. If the natural rhythm is disrupted, as for example in the case of people on shift work, the likelihood of developing metabolic disorders, diabetes, or cancer is significantly increased.
