Anti-TERF2IP antibodies are used in the immunodetection of the protein TERF2 interacting protein. In humans, the canonical protein has a reported length of 399 amino acid residues and a mass of 44.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is ubiquitously expressed across many tissue types. A member of the RAP1 protein family, TERF2IP is known to act both as a regulator of telomere function and as a transcription regulator. Synonyms for this target antigen include RAP1, telomeric repeat-binding factor 2-interacting protein 1, TERF2-interacting telomeric protein 1, TRF2-interacting telomeric RAP1 protein, and DRIP5. TERF2IP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 80 citations in the literature describe the use of TERF2IP antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
