General annotation (Comments)

Function

Mediates the uptake of glutamate into synaptic vesicles at presynaptic nerve terminals of excitatory neural cells. May also mediate the transport of inorganic phosphate. Ref.1 Ref.3 Ref.4 Ref.5 Ref.6 Ref.10

Subcellular location

Cytoplasmic vesicle › secretory vesicle › synaptic vesicle membrane. Membrane; Multi-pass membrane protein Potential. Cell junction › synapse › synaptosome Ref.3 Ref.5 Ref.6 Ref.7 Ref.8.

Tissue specificity

Expressed in the cerebellum, cerberal cortex and hippocampus. Isoform 2 is expressed specifically in retina. Ref.1 Ref.2 Ref.5 Ref.6 Ref.7

Developmental stage

Expression of isoform 2 increases sharply during the first ten days of postnatal life, and also increases with increasing numbers of rhodopsin cells in the retina. Ref.2

Induction

Induced within cerebellar granule cells by exposure to N-methyl-D-aspartate (NMDA). Ref.1

Sequence similarities

Belongs to the major facilitator superfamily. Sodium/anion cotransporter family. VGLUT subfamily.
