Dinucleoside polyphosphates : newly detected uraemic compounds with an impact on leucocyte oxidative burst [PDF]
, 2009 Background. Dinucleoside polyphosphates (NpnN) have pathophysiologic roles in cardiovascular disease and are newly detected uraemic retention solutes. They were retrieved in human plasma, tissues and cells.

The T2238C human atrial natriuretic peptide molecular variant and the risk of cardiovascular diseases [PDF]
, 2018 Atrial natriuretic peptide (ANP) is a cardiac hormone which plays important functions to maintain cardio-renal homeostasis. The peptide structure is highly conserved among species. However, a few gene variants are known to fall within the human ANP gene.

Crosstalk between G-protein and Ca2+ pathways switches intracellular cAMP levels [PDF]
, 2001 Cyclic adenosine monophosphate and cyclic guanosine monophosphate are universal intracellular messengers whose concentrations are regulated by molecular networks comprised of different isoforms of the synthases adenylate cyclase or guanylate cyclase and ...

Gαs slow conformational transition upon GTP binding and a novel Gαs regulator
iScience, 2023 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

Nonenzymatic Formation of Guanosine 3′ : 5′-Monophosphate from Guanosine Triphosphate
Journal of Biological Chemistry, 1974 Abstract We observed the nonenzymatic formation of guanosine 3' : 5'-monophosphate (cyclic GMP) from GTP. The reaction was dependent upon heat and was accelerated by divalent cations and creatine phosphate. The formation of cyclic GMP was greater with increased incubation time, temperature, GTP concentration, and pH. All of the divalent cations tested (

Role of ARHGEF3 as a GEF and mTORC2 Regulator
Frontiers in Cell and Developmental Biology, 2022 Guanine nucleotide exchange factors (GEFs) activate GTPases by stimulating the release of guanosine diphosphate to permit the binding of guanosine triphosphate.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]
, 2002 Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

RhoB regulates cell migration through altered focal adhesion dynamics [PDF]
Open Biology, 2012 The Rho GTPase RhoB has been shown to affect cell migration, but how it does this is not clear. Here we show that cells depleted of RhoB by RNAi are rounded and have defects in Rac-mediated spreading and lamellipodium extension, although they have active

Dynamics of Microtubule Growth and Catastrophe [PDF]
, 2007 We investigate a simple model of microtubule dynamics in which a microtubule evolves by: (i) attachment of guanosine triphosphate (GTP) to its end at rate lambda, (ii) GTP converting irreversibly to guanosine diphosphate (GDP) at rate 1, and (iii ...
