Anti-SMIM23 antibodies are used in the immunodetection of the protein small integral membrane protein 23. In humans, the canonical protein has a reported length of 172 amino acid residues and a mass of 20 kDa. Its subcellular localization is in the cell membrane. Synonyms for this target antigen include CTB-78H18.1. SMIM23 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species.
