GABA transporter type 3

GABA transporter type 3 (GAT3) uses sodium (Na+) electrochemical gradients to mediate uptake of GABA from the synaptic cleft by surrounding glial cells.[1]

Subtype-selective GAT3 inhibitors are known since 2015.[2]

The gat3 enzyme and its effect on GABA concentrations in the amygdala has been implicated as a key player in the disease of alcoholism. In studies conducted on rat populations, reduction of the gat3 enzyme caused rats who formerly preferred sugar to prefer alcohol. Further, studies of deceased alcoholics show a decreased concentration of gat3 in their brains. https://www.theatlantic.com/science/archive/2018/06/a-landmark-study-in-the-origins-of-alcoholism/563372/
