Anti-TMPRSS11A antibodies are used in the immunodetection of the protein transmembrane serine protease 11A. In humans, the canonical protein has a reported length of 418 amino acid residues and a mass of 47.3 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in esophagus, liver, colon and lung. A member of the Peptidase S1 protein family, TMPRSS11A is a suspected serine protease which may play a role in cellular senescence. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include airway trypsin-like protease 1, epidermal type-II transmembrane serine protease, esophageal cancer-susceptibility gene 1 protein, transmembrane protease, serine 11A, and transmembrane protease serine 11A. TMPRSS11A gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is a widely used application for the TMPRSS11A antibodies listed below. In addition, ELISA is also a common application.
