Background: p53

The p53 tumor suppressor protein is a multi-functional transcription factor that regulates proliferation, cell cycle checkpoints, and apoptosis. The importance of p53 is underscored by its mutation in over 50% of human cancers. Human p53 is a 393 amino acid (aa) nuclear/cytoplasmic protein that contains an N-terminal activation domain, a specific DNA binding domain, and a C-terminal domain that mediates tetramer formation and regulates DNA binding. P53 is phosphorylated on Ser15 in response to irradiation, and this phosphorylation increases recruitment of the coactivator CREB-binding protein/p300. The ATM or ATR kinases can phosphorylate p53 at serine 15 (S15), which leads to cell cycle arrest. Serine 15 phosphorylation leads to p53 stabilization and enhances transactivation of p53 target genes.
