| Abstract | ||
| P53 is a 393 residue protein in humans made up of five proposed domains, with which the central DNA binding domain with 100-300 sequences very important for the direct binding of p53 in the promoters of its target genes to specific response elements. P53 is a tumor suppressor gene with cellular stress like oxygen deficiency, oxidative stress, radiation and carcinogens substances, is stimulated has major roles in translational regulation and feedback processes. A wide assortment of harm signals that relate a stability, post-translational alteration and recruitment of p53 to binding sites in chromatin which activate the p53 pathway. As a transcriptional activation, p53 mediates transcriptional changes which facilitate cell death, senescence or reversing and protective arrest of the cell cycle. P53 is a protein under intense investigation because it is necessary to prevent tumor, in human tumors have been found to deregulation of p53 activity. On this article study focuses the mechanism of suppressive p53 effects in the response to any stress and correlation of the mutation p53 with different tumor. | ||
