Target intelligence / Profile preview

Purinergic Receptor P2Y1 Subtype (P2RY1)

Target
P2RY1
Molecular classification
G protein-coupled receptor, GPCR, Class A GPCR, Purinergic receptor
01

Overview

The purinergic receptor P2Y₁ plays a central role in platelet activation/aggregation through its response to extracellular nucleotides like ADP, making it a significant target for antithrombotic therapies. Its broader physiological roles are still being elucidated but likely extend into vascular biology and possibly neurobiology due to widespread tissue distribution.

02

Mechanism of action

Agonist binding leads to activation of phospholipase C and mobilization of intracellular calcium, resulting in platelet shape change and aggregation. Antagonists block ADP binding and subsequent activation.
