Previous GeneCards Identifiers for P2RY2 Gene
The product of this gene belongs to the family of P2 receptors, which is activated by extracellular nucleotides and subdivided into P2X ligand-gated ion channels and P2Y 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, found on many cell types, is activated by ATP and UTP and is reported to be overexpressed on some cancer cell types. It is involved in many cellular functions, such as proliferation, apoptosis and inflammation. Three transcript variants encoding the same protein have been identified for this gene.

GeneCards Summary for P2RY2 Gene
P2RY2 (Purinergic Receptor P2Y, G-Protein Coupled, 2) is a Protein Coding gene. Diseases associated with P2RY2 include cystic fibrosis. Among its related pathways are GPCR Pathway and Signaling by GPCR. GO annotations related to this gene include receptor activity and G-protein coupled purinergic nucleotide receptor activity. An important paralog of this gene is PTAFR.
UniProtKB/Swiss-Prot for P2RY2 Gene
Receptor for ATP and UTP coupled to G-proteins that activate a phosphatidylinositol-calcium second messenger system. The affinity range is UTP = ATP > ATP-gamma-S >> 2-methylthio-ATP = 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.
