p53 (pSer15) antibody
Rabbit anti p53 (pSer15) antibody recognizes cellular tumor antigen p53, also known as antigen NY-CO-13, phosphoprotein p53 and tumor suppressor p53, when phosphorylated at serine 15.
The p53 protein is important in multicellular organisms, where it regulates cell cycle progression to allow DNA repair or apoptosis in the case of irreparably damaged cells (Haupt et al. 2003) and thus functions as a tumor suppressor, involved in preventing cancer. Mutations in the p53 gene are found in about half the cases of human cancer (Joerger and Fersht 2007).
Rabbit anti p53 (pSer15) antibody binds to p53 phosphorylated on serine 15 in response to DNA damage. The kinases ATM, ATR, and DNA-PK are all able to phosphorylate p53 on serine 15, which impairs its capacity to bind to the E3 ubiquitin protein ligase MDM2.
