Localization of N-glycosylation sites and functional role of the carbohydrate units of GLAST-1, a cloned rat brain L-glutamate/L-aspartate transporter.

Assesses a possible role of the two glycosylation sites wild-type and glycosylation-deficient (GLAST-1) expressed in Xenopus oocytes. Characterization of function by using the whole-cell voltage-clamp technique; Results proving that the N-glycosylation has no impact on the transport activity of GLAST-1.
