Reaction: The UDP/CysLT (P2Y17) receptor can bind UTP
- in pathway: P2Y receptors
GPR17, an orphan receptor at intermediate phylogenetic position between P2Y and CysLT receptors, is specifically activated by both families of endogenous ligands, leading to both adenylyl cyclase inhibition and intracellular calcium increases. In this example, GPR17 binds to UDP. The UDP-bound receptor couples with Gq/11 and leads to intracellular calcium increases (Ciana P et al, 2006).
