Anti-RNA polymerase II, I and III subunit F antibodies are used for the immunodetection of the protein encoded by the POLR2F gene. In humans, the canonical protein has a reported length of 127 amino acid residues and a mass of 14.5 kDa. Its subcellular localization is in the nucleus. A member of the Archaeal Rpo6/eukaryotic RPB6 RNA polymerase subunit protein family, it is known to be involved with transcription by RNA polymerase II. Other names for this target antigen include POLRF, RPABC14.4, RPABC2, RPB14.4, RPB6, and HRBP14.4. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
