"Dopamine receptors 2 (Grandy DK et al, 1989), 3 (Giros B et al, 1990) and 4 (Van Tol HH et al, 1991) are members of the D2-like dopamine receptor family. Once activated, these receptors couple with the G protein alpha-i subtype which directly inhibits cAMP formation by inhibition of the enzyme adeylate cyclase."^^ . . . . . . . .
