Anti-TMG3 antibodies enable researchers to detect and measure the TMG3 antigen in biological samples. This target is a reported synonym of the PRRG3 gene, which encodes proline rich and Gla domain 3. The human version of TMG3 has a canonical amino acid length of 231 residues and a protein mass of 25.9 kilodaltons. It is reported to be localized in the membrane of cells.
