DOPAMINE RECEPTORS
... Dopamine Receptors • There are five types of dopamine receptors.D1,D2,D3,D4,D5. • We can catogorize dopamine receptors in two two main subtypes: • D1 like receptor family: the Gs protein is involved and adenylyl cyclase would be activated. The action of the enzyme causes the conversion of adenosine ...
