G-Protein Signaling

G protein coupled receptors (GPCRs) form a large family of cell surface receptors responsible for triggering cellular responses to a variety of extracellular stimuli including drugs such as opiates, and hormones such as adrenaline, serotonin, or acetylcholine. This family of receptors is an important target for pharmaceuticals. Importantly, defects in GPCR systems are responsible for a number of human diseases. At Michigan Pharmacology we study mechanisms of GPCR, G protein, and second messenger signaling at the molecular level and then translate these molecular principles into understanding how G proteins regulate cellular and organismal functions.
