The p53 tumor suppressor coordinates a multitude of cellular and organismal processes and exerts its activities mainly by activation of gene transcription. Here we describe the transcriptional activation of ectodysplasin A2 receptor (EDA2R) by p53 in a variety of cell types and tissues. We demonstrate that treatment of cancer cells with the ligand EDA-A2, known to specifically activate EDA2R, results in p53-dependent cell death. Moreover, we show that EDA2R is transactivated by p53 during chemotherapy-induced hair-loss, although its presence is not necessary for this process. These data shed new light on the role of EDA2R in exerting p53 function. © 2010 Federation of European Biochemical Societies.
