Protein found that regulates gene critical to dopamine-releasing brain cells

Researchers have identified a protein they say appears to be a primary player in maintaining normal functioning of an important class of neurons – those brain cells that produce, excrete and then reabsorb dopamine neurotransmitters. These molecules command numerous body functions, ranging from management of behavior and mood to control of movement, and one day may hold the key to why and how some people develop Parkinson's and other brain diseases.
