CRTH-2, also known as GPR44, is a 7TM G protein-coupled receptor that is
expressed by activated Th2 cells and eosinophils. CRTH-2 binds
Prostaglandin D2 and induces chemotaxis of these cells in allergic and
inflammatory immune responses. Human and mouse CRTH-2 share 78% amino
acid sequence identity.
