3,4-dihydroxyphenylacetic acid (DOPAC) is a metabolite of dopamine formed through deamination by monoamine oxidase (MAO).1 DOPAC is further metabolized by catechol-O-methyltransferase (COMT) to form homovanillic acid, and DOPAC levels are increased 5- to 6-fold compared to wild-type in the nucleus accumbens, striatum, and prefrontal cortex of COMT knockout mice. DOPAC oxidation is catalyzed by α-synuclein and oxidized DOPAC binds to monomeric α-synuclein preventing fibrillation.2 In vivo, foot shock stress increases DOPAC levels relative to control by approximately 45% in the prefrontal cortex and by 15% in the olfactory tubercles and ventral tegmental area (VTA) in rats.3
