| Common Name | Guanosine triphosphate | ||||||||||||||||||||||||||||||||||||||||
| Description | Guanosine triphosphate, also known as 5'-GTP or guanosine triphosphate, belongs to the class of organic compounds known as purine ribonucleoside triphosphates. These are purine ribobucleotides with a triphosphate group linked to the ribose moiety. Guanosine triphosphate is possibly soluble (in water) and a moderately basic compound (based on its pKa). Guanosine triphosphate exists in all living species, ranging from bacteria to humans. In cattle, guanosine triphosphate is involved in a couple of metabolic pathways, which include the intracellular signalling through adenosine receptor A2A and adenosine pathway and the intracellular signalling through adenosine receptor A2B and adenosine pathway. | ||||||||||||||||||||||||||||||||||||||||

- General function:
- Not Available
- Specific function:
- Uridine diphosphatase (UDPase) that promotes protein N-glycosylation and ATP level regulation. UDP hydrolysis promotes protein N-glycosylation and folding in the endoplasmic reticulum, as well as elevated ATP consumption in the cytosol via an ATP hydrolysis cycle. Together with CMPK1 and AK1, constitutes an ATP hydrolysis cycle that converts ATP to AMP and results in a compensatory increase in aerobic glycolysis. The nucleotide hydrolyzing preference is GDP > IDP > UDP, but not any other nucleoside di-, mono- or triphosphates, nor thiamine pyrophosphate. Plays a key role in the AKT1-PTEN signaling pathway by promoting glycolysis in proliferating cells in response to phosphoinositide 3-kinase (PI3K) signaling (By similarity).

Reactions
| Guanosine triphosphate + Water → Guanosine diphosphate + Hydrogen phosphate | details |
- General function:
- Not Available
- Specific function:
- Functions as a guanine nucleotide exchange factor (GEF), which activates Rap and Ras family of small GTPases by exchanging bound GDP for free GTP in a cAMP-dependent manner. Serves as a link between cell surface receptors and Rap/Ras GTPases in intracellular signaling cascades. Acts also as an effector for Rap1 by direct association with Rap1-GTP thereby leading to the amplification of Rap1-mediated signaling. Shows weak activity on HRAS. It is controversial whether RAPGEF2 binds cAMP and cGMP or not. Its binding to ligand-activated beta-1 adrenergic receptor ADRB1 leads to the Ras activation through the G(s)-alpha signaling pathway. Involved in the cAMP-induced Ras and Erk1/2 signaling pathway that leads to sustained inhibition of long term melanogenesis by reducing dendrite extension and melanin synthesis. Provides also inhibitory signals for cell proliferation of melanoma cells and promotes their apoptosis in a cAMP-independent nanner. Regulates cAMP-induced neuritogenesis by mediating the Rap1/B-Raf/ERK signaling through a pathway that is independent on both PKA and RAPGEF3/RAPGEF4. Involved in neuron migration and in the formation of the major forebrain fiber connections forming the corpus callosum, the anterior commissure and the hippocampal commissure during brain development. Involved in neuronal growth factor (NGF)-induced sustained activation of Rap1 at late endosomes and in brain-derived neurotrophic factor (BDNF)-induced axon outgrowth of hippocampal neurons. Plays a role in the regulation of embryonic blood vessel formation and in the establishment of basal junction integrity and endothelial barrier function. May be involved in the regulation of the vascular endothelial growth factor receptor KDR and cadherin CDH5 expression at allantois endothelial cell-cell junctions (By similarity). Binds to cAMP.
