Structure of Circadian Rhythm Protein Discovered

Structural biologists at the Institute of Molecular Biology  have made important progress towards better understanding the functioning of the circadian clock. The circadian or inner clock coordinates the sleep-wake rhythm and many other body processes that regulate metabolism, blood pressure, and the immune system. They have discovered for the first time identified the molecular structure of a protein complex that plays an important role in regulating the circadian rhythm.
Using x-ray identification, scientists were able to observe the atomic interactions between the protein and the zinc ion that mediates it. They discovered that the zinc ion acted as a stabilizing agent for the protein. These discoveries will help to treat sleep disorders such as insomnia, or narcolepsy. It can also be used to study variations in sleep patterns among different age and gender demographics.

NOS themes- Science is collaborative- A group of researchers from many different universities discovered the structure of this protein.
