Anti-VGAT antibodies are used in antigen-specific immunodetection in biological samples. The target VGAT is a known alias name of the protein solute carrier family 32 member 1, encoded by the SLC32A1 gene in humans. This 525-amino acid residue protein is a reported antiporter that exchanges vesicular protons for cytosolic 4-aminobutanoate or to a lesser extend glycine, thus allowing their secretion from nerve terminals. It is localized to the cytoplasmic vesicles of the cell. It is reported to be expressed in the retina, cerebral cortex, and cerebellum.
