AATF (Apoptosis Antagonizing Transcription Factor, CHE1, CHE-1, DED, HSPC277, Protein AATF, Rb-binding Protein Che-1)

AATF (apoptosis antagonizing transcription factor) was initially discovered as an interaction partner of ZIP kinase (ZIPK), a member of death-associated protein (DAP) kinase family of pro-apoptotic serine/threonine kinases. AATF is a phosphoprotein containing an acidic region and a putative leucine zipper domain and nuclear localization signal, features which are typical of transcription factors. AATF inhibits the ZIPK-mediated pro-apoptotic pathway and may activate other anti-apoptotic pathways. Recently, it has also been shown to protect neural cells against oxidative damage induced by amyloid b-peptide and to inhibit aberrant production of the b-peptide by interacting with Par-4 (prostate apoptosis response-4), another pro-apoptotic leucine zipper protein that is associated with neuronal degeneration in Alzheimer's disease (AD), suggesting that AATF may have potential therapeutic applications in both familial and sporadic forms of AD.\n\nApplications:\nSuitable for use in ELISA, Western Blot, Immunofluorescence and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 0.5-2ug/ml\nImmunofluorescence: 20ug/ml\nImmunohistochemistry (Formalin fixed paraffin embedded): 10ug/ml\nOptimal dilutions to be determined by the researcher.\n\nPositive Control:\nHuman Small Intestine Tissue Lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
