Recently identified protein group plays major role in nature

Proteins are the 'workhorses' in every living cell and constitute the chemical basis of life. These little machines are required to turn food into energy, to manage motion and brain activities and to fight off bacteria and viruses. The function of proteins is tightly controlled in response to changing conditions, when for instance an organism encounters stress and needs to adapt. Researchers recently discovered a completely novel group of proteins that functions as a switch to regulate biologica...
