Anti-ETI-1 antibodies enable researchers to detect and measure the ETI-1 antigen in biological samples. This target is a reported synonym of the SLC39A2 gene, which encodes solute carrier family 39 member 2. This protein is known to function in the transport of ions, among other biological roles. The human version of ETI-1 has a canonical amino acid length of 309 residues and a protein mass of 32.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include 6A1 and ZIP-2.
