Anti-TRF2 antibodies enable researchers to detect and measure the TRF2 antigen in biological samples. This target is a reported synonym of the TERF2 gene, which encodes telomeric repeat binding factor 2. This protein is known to function in the cell cycle and in utero embryonic development, among other biological roles. The human version of TRF2 has a canonical amino acid length of 542 residues and a protein mass of 59.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types.
