Background

TP53, also named as P53 and NY-CO-13, belongs to the p53 family that functions as a central mediator for organizing cellresponses to various stress and anticancer drugswith apoptosis,G1- phase arrest, and DNA repair.[PMID: 20346922]. In addition, TP53 appears to induce apoptosis through nontranscriptional cytoplasmic processes. In unstressed cells, TP53 is kept inactive essentially through the actions of the ubiquitin ligase MDM2, which inhibits TP53 transcriptional activity and ubiquitinates TP53 to promote its degradation[PMID: 22330136]. TP53 acts as a tumor suppressor in many tumor types and induces growth arrest or apoptosis depending on the physiological circumstances and cell type. It is involved in cell cycle regulation as a trans-activator that acts to negatively regulate cell division by controlling a set of genes required for this process.
