Enables L-glutamate transmembrane transporter activity. Acts upstream of or within L-glutamate transmembrane transport. Located in synaptic vesicle membrane. Is integral component of synaptic vesicle membrane. Is expressed in brain; cochlear ganglion; and sensory organ. Used to study autosomal dominant nonsyndromic deafness 25. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 25. Orthologous to human SLC17A8 (solute carrier family 17 member 8).
