Vesicular glutamate transporter 3 (VGLUT3) is a protein that in humans is encoded by the SLC17A8 gene.
This gene encodes a vesicular glutamate transporter. The encoded protein transports the neurotransmitter glutamate into synaptic vesicles before it is released into the synaptic cleft.
Mutations in this gene are the cause of autosomal-dominant nonsyndromic deafness type 25 (DFNA25).
