Cellular tumor antigen p53 (p53) is a ubiquitous transcription factor that is most widely known for its function as a tumor suppressor, through its regulation of cell growth and survival. p53 is activated in response to cell stress such as DNA damage and induces either cell cycle arrest or apoptosis. It coordinates the expression of multiple genes including p21, GADD45, Bax, and Puma. p53 is regulated by multiple mechanisms: At the post-transcriptional level, the stability of p53 mRNAs is regulated by the binding of molecules such as HuR, Wig-1, RPL26, L26, and WRAP53. Post-translationally, p53 undergoes phosphorylation and acetylation which may also play a role in regulating its activity. It may also undergo ubiquitination via the Akt-MDM2 pathway resulting in degradation by the 20S proteosome. Mutations in p53 are prevalent in many types of cancers, underscoring the therapeutic relevance of this protein.
