Prostaglandin E2 receptor

The prostaglandin E₂ (PGE₂) receptors are G protein-coupled receptors that bind and are activated by prostaglandin E₂. They include the following proteins:

Prostaglandin E₂ receptor 1 (EP₁) - PTGER1
Prostaglandin E₂ receptor 2 (EP₂) - PTGER2
Prostaglandin E₃ receptor 3 (EP₃) - PTGER3
Prostaglandin E₄ receptor 4 (EP₄) - PTGER4
