The ELISA kits listed below target TMPRSS4, the symbol for the human gene, transmembrane serine protease 4, and a member of the Peptidase S1 family. The protein has an enzyme classification of peptidase (broad). The protein encoded by TMPRSS4 has a predicted amino acid length of 437, a mass of 48.2 kDa, and a membrane subcellular localization. There are currently 4 reported isoforms, as well as sites of glycosylation. TMPRSS4 may also be known by the following names: MT-SP2, type II membrane serine protease, transmembrane protease serine 4, membrane-type serine protease 2, and transmembrane protease serine 4. Orthologs of the gene, including human, mouse, and rat are available targets of several ELISA kits.
