Anti-protease, serine 33 antibodies enable researchers to detect and measure the protease, serine 33 antigen in biological samples. This target is a reported synonym of the PRSS33 gene, which encodes serine protease 33. This protein is known to function in proteolysis, among other biological roles. The human version of protease, serine 33 has a canonical amino acid length of 280 residues and a protein mass of 29.8 kilodaltons. It is reported to be a secreted protein. protease, serine 33 is a member of the Peptidase S1 protein family.
