uridinetrifosfaat
Uridinetrifosfaat, usually abbreviated as UTP, is a ribonucleoside triphosphate composed of the nucleoside uridine attached to three phosphate groups. It is a high‑energy phosphate donor and an activated precursor involved in a variety of cellular processes. In many organisms, UTP sits alongside other nucleoside triphosphates as a key building block for RNA synthesis and nucleotide metabolism.
A central biological role of UTP is as a substrate for RNA synthesis. RNA polymerases use UTP,
Biosynthesis and turnover of UTP involve phosphorylation and interconversion with other nucleotides. UTP can be formed
In addition to intracellular roles, UTP also acts as an extracellular signaling molecule. It binds to purinergic
Overall, UTP is a multifunctional nucleotide involved in genetic information flow, carbohydrate activation, and signaling, reflecting
