Anti-protease, serine, 12 (neurotrypsin, motopsin) antibodies enable researchers to detect and measure the protease, serine, 12 (neurotrypsin, motopsin) antigen in biological samples. This target is a reported synonym of the PRSS12 gene, which encodes serine protease 12. This protein is known to function in exocytosis, among other biological roles. The human version of protease, serine, 12 (neurotrypsin, motopsin) has a canonical amino acid length of 875 residues and a protein mass of 97.1 kilodaltons. It is reported to be a secreted protein. Other names for this target antigen include BSSP-3, BSSP3, and MRT1.
