Glutamate/malate translocator involved with DIT1 in primary ammonia assimilation and in the re-assimilation of ammonia generated by the photorespiratory pathway. Exports the end product of ammonia assimilation, glutamate, from plastids to the cytosol. The precursor for ammonia assimilation, 2-oxoglutarate, is imported from the cytosol by DIT1. Expressed in roots, rosette and cauline leaves, stems, flowers and siliques. Non-viable seedlings under normal atmospheric conditions, but grow normally under non-photorespiratory conditions high CO(2) conditions. Belongs to the SLC13A/DASS transporter (TC 2.A.47) family. DIT1 subfamily.
