p53 is a tumor suppressor gene which encodes a transcription factor that controls cell's destiny. This gene gets activated when cells are exposed to increased cellular stress, or DNA damage. The levels of p53 are elevated when post-translational modifications occur, which block its sequestration and/or ubiquitination by its destabilizer, Mouse Double Minute 2 Homolog (MDM2) which in turn is a transcriptional target of p53. Due to the three putative nuclear localization signals (NLSs) on its C-terminus, some of the activated p53 protein translocates into the nucleus and activate genes that induce cell cycle arrest, senescence, or apoptosis. The p53 gene is frequently mutated in cancer cells, and about 50% of cancers show p53 mutations, resul
