text: PKA helps transfer/translate the dopamine signal into cells in the nucleus accumbens, which mediates reward, motivation, and task salience. The vast majority of reward perception involves neuronal activation in the nucleus accumbens, some examples of which include sex, recreational drugs, and food. Protein Kinase A signal transduction pathway helps in modulation of ethanol consumption and its sedative effects. A mouse study reports that mice with genetically reduced cAMP-PKA signalling results into less consumption of ethanol and are more sensitive to its sedative effects.
