"The CHK2 phosphorylates p53 at S20 and in turn activates it."

"Two peptides derived from the DNA-binding domain of p53 bind to CHK2 and stimulate phosphorylation of full-length p53 at Thr 18 and Ser 20, thus identifying CHK2-docking sites."

"ATM is one of the major kinases that phosphorylate p53 at Ser15 after IR and that ATM also phosphorylates and activates Chk2 after IR, which then phosphorylates p53 at Ser20"
