Anti-NAT-1 antibodies enable researchers to detect and measure the NAT-1 antigen in biological samples. This target is a reported synonym of the SLC6A2 gene, which encodes solute carrier family 6 member 2. This protein is known to function in chemical synaptic transmission and the response to xenobiotic compounds, among other biological roles. The human version of NAT-1 has a canonical amino acid length of 617 residues and a protein mass of 69.3 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the testis, soft tissue, cerebral cortex, and cerebellum. NAT-1 is a member of the Sodium:neurotransmitter symporter (SNF) (TC 2.A.22) protein family.
