Anti-NALF2 antibodies are used in the immunodetection of the protein NALCN channel auxiliary factor 2. 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, NALF2 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. Synonyms for this target antigen include FAM155B, TED, TMEM28, bB57D9.1, bB57D9.1 (TED protein), and CXorf63. NALF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
