Figure 2. Intracellular DA signaling pathways.

Figure 2

Schematic of cAMP/PKA-dependent (A) and independent (B) pathways recruited by DA receptors. D1- and D2-like receptors are depicted in the same cell for illustrative purposes. Note that some of the targets of Gβγ are ion channels (Kir3, CaV1 and CaV2.2). Black and red arrows depict activation and inhibition, respectively. IP3, inositol triphosphate; DAG, diacylglycerol.
