A human dopamine transporter cDNA predicts reduced glycosylation, displays a novel repetitive element and provides racially-dimorphic TaqI RFLPs.

We describe a cDNA for the human dopamine transporter, which has been implicated in several human disorders linked to dopaminergic function. The cDNA predicts reduced glycosylation of the protein with respect to the rat transporter, as well as a novel repetitive element in the 3' untranslated region of the cDNA. A TaqI RFLP is also reported that shows a race-specific difference in allelic frequencies.
