Anti-Matriptase 2 antibodies enable researchers to detect and measure the Matriptase 2 antigen in biological samples. This target is a reported synonym of the TMPRSS6 gene, which encodes transmembrane serine protease 6. This protein is known to function in the regulation of transcription, among other biological roles. The human version of Matriptase 2 has a canonical amino acid length of 811 residues and a protein mass of 90 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include transmembrane protease serine 6, transmembrane protease serine 6, and matriptase-2.
