'Jekyll and Hyde' protein linked to type 1 diabetes

Researchers are a step closer to establishing the link between a protein with a split personality and type 1 diabetes. New research shows how a protein, called GAD65, changes its shape when it turns itself on and off. Curiously, this characteristic may also link it to type 1 diabetes. In the human brain, GAD65 performs an essential role, making 'neurotransmitters,' chemicals that pass messages between brain cells.
