Anti-PSMP antibodies enable researchers to detect and measure the PSMP antigen in biological samples. This target is a reported synonym of the MSMP gene, which encodes microseminoprotein, prostate associated. This protein is known to function in inflammatory response pathways, among other biological roles. The human version of PSMP has a canonical amino acid length of 139 residues and a protein mass of 15 kilodaltons. It is reported to be a secreted protein. PSMP is a member of the Beta-microseminoprotein family.
