Guanosine 5'-O-(3-thiotriphosphate) inhibits capping of reovirus mRNA.
Journal of Biological Chemistry, 1982 RNA synthesized by reovirus cores was not capped or methylated when GTP was replaced by guanosine 5'-O-(3-thiotriphosphate) [gamma-S]GTP as a reaction substrate. Full length transcripts were synthesized in the presence of [gamma-S]GTP which indicated that capping could be dissociated from the process of transcription.

Guanosine 5'-O-(3-thiotriphosphate), a potent nucleotide inhibitor of microtubule assembly.
Journal of Biological Chemistry, 1984 Guanosine 5'-O-(3-thiotriphosphate) (GTP gamma S) and the two diastereoisomers of guanosine 5'-O-(2-thiotriphosphate) (GTP beta S) were prepared enzymatically, and their interactions with tubulin and microtubule-associated proteins (MAPs) in 0.1 M 2-(N-morpholino)ethanesulfonate, 0.5 mM MgCl2 were examined.

Muscarinic acetylcholine receptor‐stimulated binding of guanosine 5′‐O‐(3‐thiotriphosphate) to guanine‐nucleotide‐binding proteins in cardiac membranes [PDF]
European Journal of Biochemistry, 1989 Receptor‐regulated binding of the labeled GTP analog, guanosine 5′‐O‐(3‐thiotriphosphate) ([35S]GTP[S]), to guanine‐nucleotide‐binding proteins (G‐proteins) was studied in porcine atrial membranes enriched in muscarinic acetylcholine (mACh) receptors. Binding of [35S]GTP[S] to the membranes was not or only slightly affected by the cholinergic agonist ...

Are guanine nucleotide-binding proteins involved in regulation of thylakoid protein kinase activity? [PDF]
, 1987 The slow ATP-induced decrease in chlorophyll fluorescence associated with the phosphorylation of LHC II seen in spinach thylakoids was inhibited by GTP and its non-hydrolysable analogues β, γ-imidoguanosine 5′-triphosphate and guanosine 5′-O-(3 ...

Neurosignals, 1997 Effects of guanosine 5'-O-(3-thiotriphosphate) (GTP gamma S) and cations on 2-[125I]iodomelatonin binding were investigated in membrane preparations of the chicken spinal cord. At concentrations of 10 and 50 mumol/l, GTP gamma S dose-dependently increased (p < 0.05) the equilibrium dissociation constant (Kd) and depressed (p < 0.05) the maximum number ...

Guanosine nucleotide-dependent activation of the amiloride-blockable Na+ channel
, 1989 Effects of guanosine nucleotides on the epithelial Na+ channel were studied in apical membrane vesicles derived from the toad bladder epithelium. Trapping 10 microM guanosine-5'-O-(thiotriphosphate) (GTP gamma S) in vesicles evoked two- to fourfold ...

An Effector of Hemoglobin Structure: The Guanosine 3', 5'-Triphosphate [PDF]
, 2012 The effect of guanosine 3', 5'-triphosphate (GTP) on the hemoglobin structure was studied by UV-visible, fluorescence and circular dichroism (CD) spectroscopies, and cyclic voltammetry.

, 1979 The very useful radiolabeled ATP analog, adenosine 5-O-(3-[35S] thiotriphosphate) or [35S] ATPgammaS, has been prepared by a technique based on the thiophosphorylation of ADP that results in much higher yields of [35S] ATPgammaS than does a thiophosphate
