a G-protein coupled receptor of the rhodopsin family. This family includes hormone, neurotransmitter and light receptors. 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. May participate in control of the cell cycle and proliferation. Note: This description may include information from UniProtKB.
