Essential role of GTP in epinephrine stimulation of human fat cell adenylate cyclase
Journal of Lipid Research, 1981 The activity of epinephrine-sensitive adenylate cyclase of human fat cell ghosts is markedly enhanced by the GTP analog 5'-guanylyl-imidodiphosphate (GMP-P(NH)P), but a similar effect of GTP itself has not been heretofore demonstrable.

Blocking entry of hepatitis B and D viruses to hepatocytes as a novel immunotherapy for treating chronic infections [PDF]
, 2021 Background. Chronic hepatitis B and D virus (HBV/HDV) infections can cause cancer. Current HBV therapy using nucleoside analogues (NAs) is life-long and reduces but does not eliminate the risk of cancer.

Identifying conformational changes with site-directed spin labeling reveals that the GTPase domain of HydF is a molecular switch [PDF]
, 2017 [FeFe]-hydrogenases catalyse the reduction of protons to hydrogen at a complex 2Fe[4Fe4S] center called H-cluster. The assembly of this active site is a multistep process involving three proteins, HydE, HydF and HydG.

Dual positive and negative regulation of GPCR signaling by GTP hydrolysis [PDF]
, 2009 G protein-coupled receptors (GPCRs) regulate a variety of intracellular pathways through their ability to promote the binding of GTP to heterotrimeric G proteins. Regulator of G protein signaling (RGS) proteins increase the intrinsic GTPase activity of G-

Biopolymers, 2016 Dynamin superfamily proteins are multidomain mechano‐chemical GTPases which are implicated in nucleotide‐dependent membrane remodeling events. A prominent feature of these proteins is their assembly‐ stimulated mechanism of GTP hydrolysis.

Going in GTP cycles in the nucleolus [PDF]
The Journal of Cell Biology, 2005 Proteins are directed to cellular compartments by specific localization signals. A GTP-driven cycle has now been identified as a mechanism for protein targeting to the nucleolus. The involvement of a GTP switch suggests that nucleolar localization can be regulated and may be responsive to extracellular stimuli via signaling pathways.

GTP Binding Assays in Arabidopsis thaliana
Bio-Protocol, 2013 Signaling through G proteins constitutes an ancient mechanism that functions in the transduction of extracellular signals into intracellular responses. Activation of a proper receptor by a stimuli leads to an exchange of GDP for GTP, the activation of G ...
