			The homologue in DNA is ] (TTP or dTTP). UTP also has a deoxyribose form (dUTP).
⚫	UTP also has the role of a source of energy or an activator of substrates in metabolic reactions, like that of ], but more specific. When UTP activates a substrate, UDP-substrate is usually formed and inorganic phosphate is released.

			==Role in receptor mediation==
			UTP also has roles in mediating responses by extracellular binding to the P2Y receptors of cells. UTP and its derivatives are still being investigated for their applications in human medicine. However, there is evidence from various model systems to suggest it has applications in pathogen defense and injury repair. In mice UTP has been found to interact with P2Y4 receptors to mediate an enhancement in antibody production.<ref>{{Cite journal |last1=Iwaki |first1=Yoshimi |last2=Sakai |first2=Yusuke |last3=Ochiai |first3=Kenji |last4=Umemura |first4=Takashi |last5=Sunden |first5=Yuji |date=2014-03-01 |title=Enhancement of antibody production against rabies virus by uridine 5′-triphosphate in mice |journal=Microbes and Infection |volume=16 |issue=3 |pages=196–202 |doi=10.1016/j.micinf.2013.11.012 |pmid=24309427 |issn=1286-4579|doi-access=free }}</ref> In Schwannoma cells, UTP binds to the P2YP receptors in the event of damage.  This leads to the downstream signal cascade that leads to the eventual injury repair.<ref>{{Cite journal |last1=Lamarca |first1=Aloa |last2=Gella |first2=Alejandro |last3=Martiañez |first3=Tania |last4=Segura |first4=Mònica |last5=Figueiro-Silva |first5=Joana |last6=Grijota-Martinez |first6=Carmen |last7=Trullas |first7=Ramón |last8=Casals |first8=Núria |date=2014-06-06 |editor-last=Zegers |editor-first=Mirjam M. |title=Uridine 5′-Triphosphate Promotes In Vitro Schwannoma Cell Migration through Matrix Metalloproteinase-2 Activation |journal=PLOS ONE |language=en |volume=9 |issue=6 |pages=e98998 |doi=10.1371/journal.pone.0098998 |pmid=24905332 |pmc=4048211 |issn=1932-6203 |doi-access=free |bibcode=2014PLoSO...998998L }}</ref>
