Analysis of GTP-binding potein function with a photoaffinity GTP analog.
Folia Pharmacologica Japonica, 1995 The mechanism whereby hormones or neurotransmitters activate G proteins and their intracellular effectors can be studied in reconstituted systems using purified components. However, the regulation of receptor-G protein signaling appears to be substantially more complex in the cell and several additional components participate in this event.

The GDP-GTP exchange factor collybistin: an essential determinant of neuronal gephyrin clustering [PDF]
, 2004 Glycine receptors (GlyRs) and specific subtypes of GABA(A) receptors are clustered at synapses by the multidomain protein gephyrin, which in turn is translocated to the cell membrane by the GDP-GTP exchange factor collybistin.

Effect of Tubulin Self-Association on GTP Hydrolysis and Nucleotide Exchange Reactions [PDF]
, 2022 Tubulin nucleation, microtubule (MT) assembly, stability, and dynamics depend on GTP hydrolysis and nucleotide exchange reactions. We investigated how the self-association of isolated tubulin dimers affects the rate of GTP hydrolysis and the equilibrium

Analytical Chemistry, 2014 Thiopurine drugs are widely used as antileukemic drugs and immunosuppressive agents, and 6-thioguanosine triphosphate ((S)GTP) is a major metabolite for these drugs. Recent studies have suggested that thiopurine drugs may exert their cytotoxic effects partly through binding of (S)GTP to a GTP-binding protein, Rac1.

GTP cyclohydrolase I utilizes metal‐free GTP as its substrate [PDF]
European Journal of Biochemistry, 2003 GTP cyclohydrolase I (GCH) is the rate‐limiting enzyme for the synthesis of tetrahydrobiopterin and its activity is important in the regulation of monoamine neurotransmitters such as dopamine, norepinephrine and serotonin. We have studied the action of divalent cations on the enzyme activity of purified recombinant human GCH expressed in Escherichia ...

RalA and RalB Function as the Critical GTP Sensors for GTP-Dependent Exocytosis [PDF]
The Journal of Neuroscience, 2007 Although it has been established that the activation of GTPases by non-hydrolyzable GTP stimulates neurotransmitter release from many different secretory cell types, the underlying mechanisms remain unclear. In the present study we aimed to elucidate the functional role(s) for endogenous Ras-like protein A (RalA) and RalB GTPases in GTP-dependent ...
