Anti-PAUF antibodies enable researchers to detect and measure the PAUF antigen in biological samples. This target is a reported synonym of the ZG16B gene, which encodes zymogen granule protein 16B. The human version of PAUF has a canonical amino acid length of 208 residues and a protein mass of 22.7 kilodaltons. It is reported to be a secreted protein that is notably expressed in the salivary gland. PAUF is a member of the Jacalin lectin protein family.
