Anti-GLT-1 antibodies enable researchers to detect and measure the GLT-1 antigen in biological samples. This target is a reported synonym of the SLC1A2 gene, which encodes solute carrier family 1 member 2. This protein is known to function in chemical synaptic transmission and the transport of ions, among other biological roles. The human version of GLT-1 has a canonical amino acid length of 574 residues and a protein mass of 62.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the hippocampus, cerebral cortex, cerebellum, and caudate. GLT-1 is a member of the Dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) protein family.
