Anti-tamo antibodies enable researchers to detect and measure the tamo antigen in biological samples. This target is a reported synonym of the SPATA2 gene, which encodes spermatogenesis associated 2. This protein is known to function in spermatogenesis, among other biological roles. The human version of tamo has a canonical amino acid length of 520 residues and a protein mass of 58.4 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. tamo is a member of the SPATA2 protein family.
