Trf2 Antibody detects endogenous levels of Trf2 protein.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide correspoding to residues near the carboxy terminus of human Trf2. Antibodies are purified by protein A and peptide affinity chromatography.

Telomeres, the linear ends of chromosomes, are organized into T-loops to prevent them from being recognized by the cell as DNA double stranded breaks (DSBs) (1). The telomeric repeat binding factor proteins TRF1 and TRF2 bind to double-stranded telomeres to allow formation of T-loops (2). A large number of proteins involved in the DNA damage response are found physically associated with TRF2 within telomeres (3). Interestingly, TRF2 can transiently localize to DNA damage-induced DSBs, but overexpression of TRF2 prevents ATM-dependent signaling (4). Phosphorylation of TRF2 at Ser323 has been reported in vivo, but no upstream kinase or role has been established for this phosphorylation site (5).
