A variety of transporters with affinity for glutamate

The glutamate transporters (Excitatory Amino Acid Transporters; EAATs) are indicated in red. These are found in the plasma membranes. The glutamate-cystine exchanger (xCT) uses the transmembrane gradient of glutamate to import cystine needed for glutathione synthesis. The vesicular glutamate transporters (VGLUTs) pack glutamate into synaptic vesicles (for review see: Danbolt, 2001)
