Anti-SLC4A7 antibodies are used in the immunodetection of the protein solute carrier family 4 member 7. In humans, the canonical protein has a reported length of 1214 amino acid residues and a mass of 136 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 14 different isoforms for this protein. It is reported to be highly expressed in testis and spleen. A member of the Anion exchanger (TC 2.A.31) protein family, it is known to be involved with transmembrane transport. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include NBC3, SBC2, SLC4A6, sodium bicarbonate cotransporter 3, and NBC2.
