Previous GeneCards Identifiers for P2RY4 Gene
The product of this gene belongs to the family of G-protein coupled receptors. This family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various adenosine and uridine nucleotides. This receptor is responsive to uridine nucleotides, partially responsive to ATP, and not responsive to ADP. [provided by RefSeq, Jul 2008]
GeneCards Summary for P2RY4 Gene
P2RY4 (Pyrimidinergic Receptor P2Y, G-Protein Coupled, 4) is a Protein Coding gene. Among its related pathways are GPCR Pathway and Signaling by GPCR. GO annotations related to this gene include G-protein coupled purinergic nucleotide receptor activity and UTP-activated nucleotide receptor activity. An important paralog of this gene is PTAFR.
UniProtKB/Swiss-Prot for P2RY4 Gene
Receptor for UTP and UDP coupled to G-proteins that activate a phosphatidylinositol-calcium second messenger system. Not activated by ATP or ADP
P2Y receptors are G-protein-coupled receptors that respond to extracellular purine and pyrimidine nucleotides. To date eight mammalian P2Y receptors are known (P2Y1, P2Y2, P2Y4, P2Y6, P2Y11, P2Y12, P2Y13 and P2Y14) as well as the non-mammalian chick p2y3, Xenopus p2y8 and turkey p2y receptors. p2y9 and p2y10 receptors are considered to be orphan receptors, and p2y5 is now known to actually be a leukotriene B4 receptor. P2Y receptor signaling is mediated through coupling to G proteins, mainly Gq/11, with P2Y12, P2Y13 and P2Y14 signaling through Gi/o. Activation of P2Y receptors initiates a wide range of signaling cascades including PLCbeta, PLD, PLA2, AC and MAPK/MEK kinase. P2Y receptors are found in most human tissues. They have diverse physiological roles including regulation of platelet aggregation, muscle contraction, neurotransmission, and epithelial cell communication and migration.
