Anti-protease, serine 12 antibodies are used in antigen-specific immunodetection in biological samples. The target protease, serine 12 is a known alias name of the protein serine protease 12, encoded by the PRSS12 gene in humans. This 875-amino acid residue protein is reported to play a role in neuronal plasticity and the proteolytic action may subserve structural reorganizations associated with learning and memory operations. The protein is secreted and features glycosylated post-translational modifications. Other synonyms for protease, serine 12 include BSSP-3, BSSP3, and MRT1.
