Scientists map one of life's molecular mysteries

Tue, 31 Jan 2012 14:00:00 +0200

All living organisms are made up of cells, behind these intricate life forms lie complex cellular processes that allow our bodies to function. Researchers working on protein secretion - a fundamental process in biology - have revealed how protein channels in the membrane are activated by special signals contained in proteins destined for secretion. The results help explain the underlying mechanism responsible for the release of proteins such as hormones and antibodies into the blood stream.
