Scientific Data Images for Human TRF2 Antibody

Detection of Human TRF2 antibody by Western Blot.

Detection of Human TRF2 by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 2 µg/mL of Human TRF2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5635) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for TRF2 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: TRF-2

TRF2 (telomeric repeat-binding factor 2; also telomeric DNA-binding protein) is a 55‑60 kDa, ubiquitously expressed nuclear protein that participates in telomere homeostasis. TRF2 binds as a dimer to TTAGGG repeats at ends of chromosomes (telomeres), where it blocks inappropriate activation of the ATM/p53 pathway. It also collaborates with TRF1 to promote normal telomere length. TRF2 has been found up regulated in several human cancers. Human TRF2 is 500 amino acids (aa) in length. It contains an N-terminal Arg-rich region (aa 13‑30), a dimerization domain (aa 46‑112), an NLS (aa 329‑333), and a DNA binding HTH myb-type domain (aa 442‑499). There is one potential alternate start site 42 aa upstream of the standard start site, and one splice form that shows a 13 aa substitution for aa 239‑500. Over aa 78‑238, human TRF2 shares 96% aa identity with mouse TRF2.
