WebDNA damage is one of the most extensively studied p53 activation mechanism. p53 phosphorylation at the N-terminus decreases affinity for MDM2, preventing p53 degradation and leading to excess accumulation. Phosphorylation at the carboxy terminus of p53 enhances DNA binding. Product Details Images WebExpression levels of p53 and reporters of p53 function (MDM2, p53, Phospho-p53 [Ser15], TIGAR and p21 [CDKN1A]) were examined by western blotting. Results: HPV-positive …

WebApr 15, 2013 · However, AMPK also induces phosphorylation of p53 at Ser15, which stabilizes the protein and leads to mitochondrial accumulation of p53. At the mitochondrial surface, phospho-p53 adjoins and rearranges the Bak–Bcl-x L complex (Fig. S3N), resulting in conformational activation of Bak and apoptotic sensitization. This mechanism may act … WebA synthetic phospho-peptide corresponding to residues surrounding Ser15 of human phospho p53.
