Anti-small integral membrane protein 26 antibodies are used for the immunodetection of the protein encoded by the SMIM26 gene. In humans, the canonical protein has a reported length of 95 amino acid residues and a mass of 10.9 kDa. Its subcellular localization is in the membrane. Other names for this target antigen include long intergenic non-protein coding RNA 493. Gene orthologs have been identified in the mouse, rat and bovine species.
