Under normal conditions, levels of p53 protein are very low due to rapid turnover. Activation of cellular stress pathways causes covalent modification and tetramerization of p53, stabilizing the protein and leading to accumulation within the nucleus. how to sign in to outlook emailWebbNormally, wild-type p53 protein (wtp53) is either degraded or bound to a negative regulator and is inactive. When damage to DNA occurs within a cell, p53 protein is induced and causes cell cycle arrest. This gives cells a chance to repair, but if damage is too severe, cells undergo apoptosis and are rejected. nourish move love 15 minute yoga
