Anti-sodium channel epithelial 1 subunit delta antibodies are used for the immunodetection of the protein encoded by the SCNN1D gene. In humans, the canonical protein has a reported length of 802 amino acid residues and a mass of 87.9 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the Amiloride-sensitive sodium channel (TC 1.A.6) protein family, it is known to be involved with the transport of ions. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include ENaCdelta, SCNED, dNaCh, amiloride-sensitive sodium channel subunit delta, delta-ENaC, and ENaCd. Gene orthologs have been identified in the mouse, rat, bovine and chicken species.
