Anti-RNA polymerase III subunit GL antibodies are used for the immunodetection of the protein encoded by the POLR3GL gene. In humans, the canonical protein has a reported length of 218 amino acid residues and a mass of 25.3 kDa. Its subcellular localization is in the nucleus. It is widely expressed across many tissue types. It is a member of the Eukaryotic RPC7 RNA polymerase subunit protein family. The gene encoding this protein is implicated in Short stature, oligodontia, dysmorphic facies, and motor delay. Other names for this target antigen include DNA-directed RNA polymerase III subunit G-like, RNA polymerase III 32 kDa beta subunit, RNA polymerase III subunit C7-like, and DNA-directed RNA polymerase III subunit RPC7-like. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
