Anti-NALCN channel auxiliary factor 2 antibodies are used for the immunodetection of the protein encoded by the NALF2 gene. In humans, the canonical protein has a reported length of 472 amino acid residues and a mass of 52.5 kDa. Its subcellular localization is in the membrane. A member of the NALF protein family, it is a suspected component of the NALCN channel complex, a channel that regulates the resting membrane potential and controls neuronal excitability. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include FAM155B, TED, TMEM28, bB57D9.1, bB57D9.1 (TED protein), and CXorf63. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
