Binding of MDM2 regulates p53 activity by targeting p53 for degradation and inhibits p53- induced cell cycle arrest and apoptosis TARGETING THE MDM2-P53 PATHWAY FOR CANCER THERAPY: MORE THAN BINDING SITES. Our discussion, so far, has established that the tumor suppressor p53, in response to cellular stress, is activated and mediates responses such as cell cycle arrest, apoptosis, senescence and differentiation, thereby limiting malignant progression. The main regulator of p53 is the E3 ubiquitin ligase MDM2, which binds.

p53 stimulates a wide network of signals that act through two major apoptotic pathways: extrinsic pathways and intrinsic pathways. The extrinsic pathway involves engagement of particular death receptors that belong to the tumor TNFR (Tumor Necrosis Factor Receptor) family and, through the formation of the DISC (Death-Inducing-Signaling-Complex), leads to a cascade of activation of caspases. p53-Protein s, ein nukleäres Phosphoprotein, bestehend aus 393 Aminosäuren (relative Molekülmasse 53.000), das als Transkriptionsfaktor fungiert und zur Gruppe der Tumorsuppressorproteine (Tumorsuppressorgene) zählt.Das Molekül enthält verschiedene Domänen ( vgl.
