Anti-Pop3 antibodies enable researchers to detect and measure the Pop3 antigen in biological samples. This target is a reported synonym of the PYDC5 gene, which encodes pyrin domain containing 5. This protein is known to function in viral immune response and inflammatory response pathways, among other biological roles. The human version of Pop3 has a canonical amino acid length of 113 residues and a protein mass of 12.7 kilodaltons.
