MSH: Regulatory proteins that act as molecular switches. They control a wide range of biological processes including: receptor signaling, intracellular signal transduction pathways, and protein synthesis. Their activity is regulated by factors that control their ability to bind to and hydrolyze GTP to GDP. EC 3.6.1.-.,CSP: family of small membrane-bound proteins which, in the presence of GTP/GDP, transduce signals from receptor to effector molecules across the membrane; do not use for other guanine nucleotide binding proteins.,NCI: G Proteins are a family of small membrane-bound regulatory proteins that act as GTP/GDP-binding molecular switches controlling a wide range of biological processes including: transmembrane receptor signaling, intracellular signal transduction pathways, and protein synthesis. Their activity is regulated by factors that control their ability to bind to and hydrolyze GTP to GDP.
