Receptors responsive to extracellular uracil nucleotides [PDF]
Drug Development Research, 1998 The cloning of P2Y 4 and P2Y 3 (chicken) / P2Y 6 (rat, human) receptors has been the ultimate proof that receptors for pyrimidine nucleotides exist. However, on the basis of their structure these receptors do not constitute a family of their own but belong to the P2Y family, which thus encompasses selective purinoceptors (P2Y 1 , P2Y 11 ), nucleotide

Uracil nucleotides: From metabolic intermediates to neuroprotection and neuroinflammation
Biochemical Pharmacology, 2008 Uracil nucleotides (i.e., UTP and UDP) have been known for years as fundamental intermediates in the de novo synthesis of the other pyrimidine nucleotides, which altogether represent key building blocks for nucleic acid synthesis. In addition, their sugar conjugates (i.e., UDP-glucose and UDP-galactose) enter in several biochemical routes, for example ...

Enzymic determination of uracil nucleotides in tissues
Analytical Biochemistry, 1970Abstract An enzymic assay for the sequential determination of UDP-glucose, UDP-galactose, UTP, UDP, and 5′-UMP in tissues is described. Two moles of NAD are reduced per mole of uracil nucleotide by use of UDPG dehydrogenase as indicator enzyme. The procedure is highly specific for the measurement of uridine 5′-phosphates.

Effects of galactose on human leukocyte uracil nucleotides
International Journal of Biochemistry & Cell Biology, 1975Abstract 1. 1. Uracil nucleotide contents of human leukocytes were determined by enzymatic analysis. The labelling pattern of uracil nucleotides was studied after incubation of the cells in the presence of [ 14 C]uridine followed by separation of the labelled nucleotides by paper chromatography. 2. 2. A depression of UTP, UDP, and UDP-glucose

Potential signalling roles for utp and udp: sources, regulation and release of uracil nucleotides
Trends in Pharmacological Sciences, 1997Increasing evidence for receptors for uracil nucleotides has focused interest on specific signalling mechanisms involving UTP and UDP. At least three metabotropic P2 receptors are stimulated by uracil nucleotides with equal or greater potency than by adenine nucleotides, and there might be ionotropic receptors as well.

Stimulation of mouse cultured sympathetic neurons by uracil but not adenine nucleotides
Neuroscience, 2001Cultured neurons from the paravertebral sympathetic chain of rats possess excitatory P2X as well as excitatory uracil nucleotide-sensitive P2Y receptors. Preliminary observations had indicated that the analogous neurons of mice lacked P2X receptors. This difference was now investigated.
