Guanosine triphosphate (tritris)

Guanosine triphosphate tritris (GTP tritris) serves as a vital enhancer of myogenic cell differentiation and plays a critical role in modulating miRNA-myogenic regulator factors. It also facilitates the release of exosomes enriched with guanosine and guanosine-derived molecules, and is regarded as an activated precursor for RNA synthesis. In mitochondrial function, GTP participates in the import of proteins into the matrix, which is essential for various regulated pathways, and is involved in initiating peptide synthesis through the binding of formylmethionyl-tRNA to the ribosome, as well as polypeptide chain elongation. Additionally, GTP acts as a phosphate and pyrophosphate carrier that channels chemical energy into specific biosynthetic pathways. It activates signal transducing G proteins that regulate cellular processes such as proliferation and differentiation, and its hydrolysis by small GTPases, including Ras and Rho, is integral to both proliferation and apoptosis. Furthermore, the small GTPase Rab is instrumental in vesicle docking, fusion, and formation. Beyond signal transduction, GTP is an energy-rich precursor in the enzymatic biosynthesis of DNA and RNA.
