Anti-TESSP1 antibodies enable researchers to detect and measure the TESSP1 antigen in biological samples. This target is a reported synonym of the PRSS41 gene, which encodes serine protease 41. This protein is known to function in proteolysis, among other biological roles. The human version of TESSP1 has a canonical amino acid length of 318 residues and a protein mass of 35.1 kilodaltons. It is reported to be localized in the cell membrane of cells. TESSP1 is a member of the Peptidase S1 protein family.
