Elevated levels of plasma phenylalanine in schizophrenia: a guanosine triphosphate cyclohydrolase-1 metabolic pathway abnormality? [PDF]
PLoS ONE, 2014 BACKGROUND: Phenylalanine and tyrosine are precursor amino acids required for the synthesis of dopamine, the main neurotransmitter implicated in the neurobiology of schizophrenia.

Guanosine triphosphate links MYC-dependent metabolic and ribosome programs in small-cell lung cancer. [PDF]
J Clin Invest, 2021 MYC stimulates both metabolism and protein synthesis, but it is unknown how cells coordinate these complementary programs. Previous work reported that in a subset of small cell lung cancer (SCLC) cell lines, MYC activates guanosine triphosphate (GTP ...

Rho GTPases in Skeletal Muscle Development and Homeostasis [PDF]
Cells, 2021 Rho guanosine triphosphate hydrolases (GTPases) are molecular switches that cycle between an inactive guanosine diphosphate (GDP)-bound and an active guanosine triphosphate (GTP)-bound state during signal transduction. As such, they regulate a wide range

A Small Guanosine Triphosphate Binding Protein PagRabE1b Promotes Xylem Development in Poplar [PDF]
Frontiers in Plant Science, 2021 Rab GTPases are the subfamily of the small guanosine triphosphate (GTP)-binding proteins which participated in the regulation of various biological processes. Recent studies have found that plant Rabs play some specific functions.

Microtubules grow by the addition of bent guanosine triphosphate tubulin to the tips of curved protofilaments. [PDF]
J Cell Biol, 2018 We used electron tomography to examine microtubules (MTs) growing from pure tubulin in vitro as well as two classes of MTs growing in cells from six species.

Rap1 Guanosine Triphosphate Hydrolase (GTPase) Regulates Shear Stress-Mediated Adhesion of Mesenchymal Stromal Cells [PDF]
BiologyIntravenously transplanted mesenchymal stromal cells (MSCs) have been shown to interact with endothelial cells and to migrate to tissues. However, intracellular signals regulating MSC migration are still incompletely understood.

Evidence that guanosine triphosphate (GTP)-binding proteins control a synaptic response in brain: effect of pertussis toxin and GTP gamma S on the late inhibitory postsynaptic potential of hippocampal CA3 neurons [PDF]
Journal of Neuroscience, 1988 These experiments show that a synaptic response in brain, namely, the late inhibitory postsynaptic potential (IPSP) of hippocampal CA3 neurons in the rat hippocampal slice, was blocked by 2 compounds affecting guanosine triphosphate (GTP)-binding ...

Maintenance of endothelial guanosine triphosphate cyclohydrolase I ameliorates diabetic nephropathy.
J Am Soc Nephrol, 2013 In diabetes, endothelial nitric oxide synthase (eNOS) produces superoxide anion rather than nitric oxide, referred to as "eNOS uncoupling," which may contribute to endothelial dysfunction, albuminuria, and diabetic nephropathy.
