Anti-RTF1 antibodies are used in the immunodetection of the protein RTF1 homolog, Paf1/RNA polymerase II complex component. In humans, the canonical protein has a reported length of 710 amino acid residues and a mass of 80.3 kDa. Its subcellular localization is in the nucleus. It is notably widely expressed in many tissue types. RTF1 is a known component of the PAF1 complex (PAF1C) which has multiple functions during transcription by RNA polymerase II and is implicated in regulation of development and maintenance of embryonic stem cell pluripotency. Synonyms for this target antigen include KIAA0252, RNA polymerase-associated protein RTF1 homolog, Rtf1, Paf1/RNA polymerase II complex component, homolog, ortholog of mouse gene trap locus 7, and GTL7. RTF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Rtf1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
