Guanosine triphosphate tritris (GTP tritris) serves as a crucial enhancer in myocyte differentiation, playing an essential role in regulating miRNA-muscle regulatory factors. It promotes the release of exosomes rich in guanine and guanine-derived molecules, and is considered an activation precursor for RNA synthesis. In mitochondrial functionality, GTP is involved in the entry of proteins into the matrix, which is vital for various regulatory pathways. It initiates peptide synthesis by facilitating the binding of formylmethionine-tRNA to the ribosome, and aids in polypeptide chain elongation. Additionally, GTP acts as a carrier for phosphates and pyrophosphates, channeling chemical energy into specific biosynthetic pathways. It activates signal transduction G proteins, regulates cellular processes such as proliferation and differentiation, and its hydrolysis by small GTPases (including Ras and Rho) is indispensable for both proliferation and apoptosis. Furthermore, the small GTPase Rab assists in vesicle docking, fusion, and formation. Beyond signal transduction, GTP is also an energy-rich precursor in the biosynthesis of DNA and RNA enzymes.
