P2RY2 Membrane Protein Introduction

Introduction of P2RY2

P2RY2 is encoded by the P2RY2 gene. It belongs to the G-protein-coupled receptor (GPCR) family which is an important drug target and approximately 34% of all FDA approved drugs targeting this family. It is one of the eight subtypes of P2Y receptors (P2RY1, P2RY2, P2RY4, P2RY6, P2RY11, P2RY12, P2RY13 and P2RY14). P2RY2 possesses seven transmembrane alpha helices and is activated by extracellular nucleotides. Meanwhile, P2RY2 is also known as ATP receptor, P2U purinoceptor 1, P2U receptor 1 and purinergic receptor.

Function of P2RY2 Membrane Protein

The activity of P2RY2 is activated by ATP and UTP, which are the natural agonists for P2RY2. After the activation of P2RY2, like other typical G protein receptor, the intracellular C-terminal of P2RY2 coupled with the G-protein resulting in the phosphorylation of the intracellular C-terminal of P2RY2 and a variety of physiological responses. P2RY2 plays an important role in initiating early inflammatory responses and mediating later regenerative responses required for wound healing, cell migration, and liver regeneration. Since P2RY2 is widely expressed in multiple tissues of our whole body and plays pathophysiological roles in various functionalities, such as lung diseases, cancer progression, and immune diseases. It is a potential therapeutic target of dry eye disease. Diquafosol tetrasodium, which is a pharmaceutical drug for the treatment of dry eye disease, is the first P2RY2 agonists. Currently, numerous agonists targeting P2RY2 are undergoing development to treat different diseases.

    Authors in this group apply interleukin-14α-transgenic mice to investigate the role of P2RY2 in autoimmune endocrinopathy. The results of this study suggest that P2Y2 receptor regulates numerous inflammatory responses because it is unregulated during salivary gland inflammation.
