Anti-APEX1 (DNA-(Apurinic or Apyrimidinic Site) Lyase, APEX Nuclease, APEN, Apurinic-apyrimidinic En

Human apurinic (apyrimidinic) endonuclease:redox-factor 1 (APE/Ref-1) is involved in the repair of DNA damage as well as in the transcriptional regulation of genes. The repair function of the protein is located on its C-terminal region. Activation of transcription factors, which occurs via a redox-based mechanism, pertains to a approximately 6kD N-terminal fragment with Cys-65 being of essential importance. Ape1/ref-1 has been shown to stimulate the DNA binding activity of numerous transcription factors that are involved in cancer promotion and progression such as Fos, Jun, NFkB, PAX, HIF-1, HLF and p53. APE/Ref-1 is part of the cellular response to oxidative stress and protects cells from the genotoxic and cytotoxic effect of oxidizing agents. Thus, specific downmodulation of APE:Ref-1 activity in tumors might be considered as a novel therapeutic approach in tumor therapy. Applications: Suitable for use in Western Blot.
