Various molecules are involved in drug addiction induced by drugs of abuse. Therefore, the mechanism of drug addiction is still not clear, and it has been a difficulty in the development of preventive and curative drugs for drug dependence. We tried to identify the molecules associated with drug dependence, and found three molecules including shati/nat8l. Recently, it has been demonstrated that the substrate for shati/nat8l is aspaltate and shati/nat8l biosynthesizes N-acetylaspartate, which exists abundantly in the mammalian brain. In this study, we investigated the physiological function of shati/nat8l and the role of shati/nat8l in drug dependence. The overexpression of shati/nat8l in the dorsal striatum of mice led to social abnormality and depression-like behavior, and worsened a part of the motor dysfunction induced by Ca2+ channel agonist BAYK 8644. The overexpression of shati/nat8l in the nucleus accumbens of mice inhibited methamphetamine-induced behavioral and biochemical abnormalities. These findings suggest that the shati/nat8l-associated system could play a role in the regulation of mental activity and motor action, and be a new target in the development of therapeutic drugs for drug dependence.
