Extracellular Guanosine 5′-Triphosphate Induces Human Muscle Satellite Cells to Release Exosomes Stuffed With Guanosine [PDF]

Frontiers in Pharmacology, 2018
The extracellular guanosine 5′-triphosphate, GTP, has been demonstrated to be an enhancer of myogenic cell differentiation in a murine cell line, not yet in human muscle cells.

Conformations and binding pockets of HRas and its guanine nucleotide exchange factors complexes in the guanosine triphosphate exchange process

Journal of Computational Chemistry, 2022
The human Son of Sevenless (SOS) activates the signal‐transduction protein Ras by forming the complex SOS·Ras and accelerating the guanosine triphosphate (GTP) exchange in Ras.

Ginsenoside Re inhibits pacemaker potentials via adenosine triphosphate-sensitive potassium channels and the cyclic guanosine monophosphate/nitric oxide-dependent pathway in cultured interstitial cells of Cajal from mouse small intestine

Journal of Ginseng Research, 2015
Background: Ginseng belongs to the genus Panax. Its main active ingredients are the ginsenosides. Interstitial cells of Cajal (ICCs) are the pacemaker cells of the gastrointestinal (GI) tract.

Nonenzymatic Formation of Guanosine 3′ : 5′-Monophosphate from Guanosine Triphosphate

Journal of Biological Chemistry, 1974
Abstract We observed the nonenzymatic formation of guanosine 3' : 5'-monophosphate (cyclic GMP) from GTP. The reaction was dependent upon heat and was accelerated by divalent cations and creatine phosphate. The formation of cyclic GMP was greater with increased incubation time, temperature, GTP concentration, and pH. All of the divalent cations tested (

Evidence that guanosine triphosphate (GTP)-binding proteins control a synaptic response in brain: effect of pertussis toxin and GTP gamma S on the late inhibitory postsynaptic potential of hippocampal CA3 neurons [PDF]

Journal of Neuroscience, 1988
These experiments show that a synaptic response in brain, namely, the late inhibitory postsynaptic potential (IPSP) of hippocampal CA3 neurons in the rat hippocampal slice, was blocked by 2 compounds affecting guanosine triphosphate (GTP)-binding ...

Exocytosis from permeabilized bovine adrenal chromaffin cells is differently modulated by guanosine 5'-[gamma-thio]triphosphate and guanosine 5'-[beta gamma-imido]triphosphate [PDF]

, 1992
1. In bovine adrenal chromaffin cells made permeable either to molecules less than or equal to 3 kDa with alphatoxin or to proteins less than or equal to 150 kDa with streptolysin O, the GTP analogues guanosine 5'-[beta gamma-imido]triphosphate (p[NH]ppG)
