G proteins, named after the fact they bond with guanine nucleotides, are largely responsible for intercellular communications within the human organism. These transmissions regulate such functions as hormone secretion, muscle contaction, and even cognition. These transmissions take place because of chemical reactions between enzymes that bind...
