GTPgammaS (GTPγS, guanosine 5'-O-[gamma-thio]triphosphate) is a nonhydrolyzable (although in some cases such as with dynamin it is slowly hydrolyzable) G-protein-activating analog of guanosine triphosphate (GTP). It has many physiological actions such as stimulation of guanine nucleotide-binding proteins, phosphoinositide hydrolysis, cyclic AMP accumulation, and activation of specific proto-oncogenes. Its 35GS labelled radioligand [³⁵S]GTPgammaS is used in autoradiography and G-protein binding studies.

The continuing spread of methamphetamine (METH) abuse has stimulated research aimed at understanding consequences of its prolonged exposure. Alterations in nigrostriatal dopamine (DA) system parameters have been characterized in experimental studies after discontinuation of long-term METH but fewer

Intracellular transport and maintenance of the endomembrane system in eukaryotes depends on formation and fusion of vesicular carriers. A seeming discrepancy exists in the literature about the basic mechanism in the scission of transport vesicles that depend on GTP-binding proteins. Some reports des

Earlier autoradiographic studies with the 5-HT2 receptor agonist [125I](±)DOI in human brain showed unexpected biphasic competition curves for various 5-HT2A antagonists. We have performed similar studies in rat brain regions with selective 5-HT2A (M100907) and 5-HT2C (SB242084) antagonists togethe
