Interaction of GTP‐binding proteins with calmodulin [PDF]
Two GTP‐binding proteins (Gi and Go), which were the substrates for islet‐activating protein, pertussis toxin, were purified from bovine cerebral cortical membranes. Both Gi and Go completely inhibited calmodulin‐stimulated cyclic nucleotide phosphodiesterase activity. The same concentrations of these proteins, however, had no appreciable effect on the

Tissue‐specific expression differences in Ras‐related GTP‐binding proteins in male rats [PDF]
The protein kinase Mechanistic Target of Rapamycin (mTOR) in Complex 1 (mTORC1) is regulated in part by the Ras‐related GTP‐binding proteins (Rag GTPases).

Targeted Quantitative Profiling of GTP-Binding Proteins in Cancer Cells Using Isotope-Coded GTP Probes. [PDF]
GTP-binding proteins play important roles in many essential biological processes, including cell signaling, trafficking, and protein synthesis. To assess quantitatively these proteins at the whole proteome level, we developed a high-throughput targeted ...

A mant-GDP Dissociation Assay to Compare the Guanine Nucleotide Binding Preference of Small GTPases
Small GTPases are cellular switches that are switched on when bound to GTP and switched off when bound to GDP. Different small GTPase proteins or those with mutations may bind to GTP or GDP with different relative affinities.

Gαs slow conformational transition upon GTP binding and a novel Gαs regulator
Summary: G proteins are major signaling partners for G protein-coupled receptors (GPCRs). Although stepwise structural changes during GPCR–G protein complex formation and guanosine diphosphate (GDP) release have been reported, no information is available

Molecular modeling study for interaction between Bacillus subtilis Obg and Nucleotides. [PDF]
The bacterial Obg proteins (Spo0B-associated GTP-binding protein) belong to the subfamily of P-loop GTPase proteins that contain two equally and highly conserved domains, a C-terminal GTP binding domain and an N-terminal glycine-rich domain which is ...

The speed of GTP hydrolysis determines GTP cap size and controls microtubule stability
Microtubules are cytoskeletal polymers whose function depends on their property to switch between states of growth and shrinkage. Growing microtubules are thought to be stabilized by a GTP cap at their ends.
