GTP-binding protein
GTP-binding protein[¦jē‚tē¦pē ′bīn·diŋ ‚prō‚tēn] (cell and molecular biology) One of a large family of heterotrimeric or monomeric proteins that bind GTP (guanosine 5′-triphosphate) as intermediaries in intracellular signaling pathways. Also known as G protein. GTO
GTO Abbreviation for Golgi tendon organ. Golgi, Camillo (gol'je) Italian pathologist, 1843–1926. Golgi apparatusA lamellar membranous organelle in almost all cells, best viewed by electron microscopy. It consists of curved parallel series of flattened sacs that are often expanded at their ends. In secretory cells, the apparatus concentrates and packages the secretory product. Its function in other cells, although apparently important, is poorly understood. Synonym: Golgi complexGolgi cellA multipolar nerve cell in the cerebral cortex and posterior horns of the spinal cord. Type I possesses long axons; type II, short axons. Synonym: Golgi neuronGolgi complexGolgi apparatus.Golgi neuronGolgi cell.Golgi tendon organ Abbreviation: GTO A spindle-shaped structure at the junction of a muscle and a tendon. The structure is thought to function as a feedback system that senses muscle tension through tendon stretch, inhibits muscle contraction of the agonist, and facilitates contraction of the antagonistic muscle. The purpose of this mechanism, known as autogenic facilitation, is to prevent overuse and damage to the muscle and corresponding joint.
