Molecular Mechanisms Underlying G Protein Coupled Receptor Signalling

Grant number: 299811

Abstract

The maintenance of optimum health and function of living cells, and consequently that of the whole organism, depends on how cells respond to a multitude of physical and chemical stimuli that continually bombard them. The majority of the chemical stimuli such as hormones and neurotransmitters impart their actions not by directly entering the cell, but instead, by binding to a specific receiver protein at the cell surface called a receptor. In one class of such receptors called G protein-coupled receptors, the transmission of the message to the interior of the cell involves yet another protein called G protein. These receptors are the most abundant type of cell surface receptors and form the t..
