多巴胺转运蛋白(dopaminetransporter，DAT)，位于中枢多巴胺能神经元末梢，是一种膜蛋白，属于Na+／Cl-依赖性转运体基因家族。其生理作用为将突触间隙内已发挥生理效应的多巴胺(DA)重新摄入突触前膜，以备再次利用，同时终止神经细胞间的信息传递。由于分子生物学技术的应用
Dopamine transporter (DAT), located at the central dopaminergic neuron terminals, is a membrane protein belonging to the Na + / Cl-dependent transporter gene family. Its physiological role is that the synaptic cleft has played a physiological effect of dopamine (DA) re-intake of the presynaptic membrane in preparation for re-use, while terminating the transmission of information between nerve cells. Due to the application of molecular biology techniques
