Anti-TMPRSS11E antibodies are used in the immunodetection of the protein transmembrane serine protease 11E. In humans, the canonical protein has a reported length of 423 amino acid residues and a mass of 47.7 kDa. Its subcellular localization is in the cell membrane and is secreted. A member of the Peptidase S1 protein family, TMPRSS11E is reported to be a serine protease, which possesses both gelatinolytic and caseinolytic activities. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include TMPRSS11E2, transmembrane protease serine 11E, serine protease DESC1, transmembrane protease serine 11E2, transmembrane protease, serine 11E, and DESC1. TMPRSS11E gene orthologs have been reported in the mouse, rat and chimpanzee species. Some TMPRSS11E antibodies may have been used in research and have associated citations. ELISA and Western Blot are common applications for these antibodies.
