2-oxoglutarate/malate translocator involved with DIT2-1 in primary ammonia assimilation and in the re-assimilation of ammonia generated by the photorespiratory pathway. Imports 2-oxoglutarate into plastids as precursor for ammonia assimilation. 2-oxoglutarate is converted to glutamate, the end product of ammonia assimilation, which is exported to the cytosol by DIT2-1. A number of isoforms are produced. According to EST sequences. Expressed in roots, rosette and cauline leaves, stems, flowers and siliques. By nitrate after two days of nitrogen deprivation and re-illumination after three days of dark adaptation. Reduced growth and amino acid levels, but growth inhibition is prevented when mutant plants are grown under non-photorespiratory high CO(2) conditions. Belongs to the SLC13A/DASS transporter (TC 2.A.47) family. DIT1 subfamily. Truncated N-terminus.
