Description générale

Guanosine 5′-triphosphate (GTP) is a purine trinucleotide. GTP is a substrate for a wide range of G-protein coupled receptor (GPCR) GTPases, as well as cell signaling and cycling-associated guanine nucleotide exchange factors (GEF). See product G3776 for RNA polymerase transcription and DNA or RNA biosynthesis applications.

Application

Guanosine 5′-triphosphate sodium salt hydrate has been used:
  • as a component of the internal solution for astrocyte patch-clamp to monitor astrocyte calcium activity from mouse amygdala slices.
  • in a solution for channel current recording in cell lines using a voltage-clamp technique.
  • to prepare internal recording solution for injectoporation to deliver genes to mechanosensory hair cells.
  • promoting the formation of G interface-mediated homodimers of human septin during the analysis of its oligomerization state by analytical size exclusion chromatography (SEC).

The small GTPase Rab5, which cycles between GDP-bound inactive and GTP-bound active forms, plays essential roles in membrane budding and trafficking in the early endocytic pathway. Rab5 is activated by various vacuolar protein sorting 9 (VPS9) domain-containing guanine nucleotide exchange

Mechanosensation is essential for various physiological processes, and it is mediated by mechanotransduction channels. Recently, we reported that TMEM150C/Tentonin 3 (TTN3) confers mechanically activated currents with slow inactivation kinetics in several cell types, including dorsal root ganglion neurons (Hong et al.

Multicellular organisms use programmed cell death to eliminate unwanted or potentially harmful cells. Improper cell corpse removal can lead to autoimmune diseases. The development of interventional therapies that increase engulfment activity could represent an attractive approach to treat such diseases.
