Enables L-glutamate transmembrane transporter activity. Involved in hippocampus development; neural retina development; and neurotransmitter loading into synaptic vesicle. Located in cytoplasmic vesicle; excitatory synapse; and pericellular basket. Is integral component of synaptic vesicle membrane. Biomarker of transient cerebral ischemia. Orthologous to human SLC17A6 (solute carrier family 17 member 6). [provided by Alliance of Genome Resources, Apr 2022]
