Dopamine receptor flow chart. Dopamine receptors are all G protein–coupled receptors, and are divided into two classes based on which G-protein they are coupled to. [1] The D 1-like class of dopamine receptors is coupled to Gα s/olf and stimulates adenylate cyclase production, whereas the D 2-like class is coupled to Gα i/o and thus inhibits adenylate cyclase production.

Since this system regulates posture and skeletal muscle tone, a result is the characteristic bradykinesia of Parkinson's.
