Ovaj gen kodira G-protein spregnuti receptor koji vezuje ne-sulfatisane članove holecistokininske (CCK) familije peptidnih hormona. Ovaj receptor je fiziološki medijator pankreasne enzimske sekrecije i kontrakcije glatkih mišića žučne kese i stomaka. U centralnom i perifernom nervnom sistemu ovaj receptor reguliše zasićenost i oslobađanje beta-endorfina i dopamina.
