Activated ATM phosphorylates ZNF420 (Apak) at serine residue S68. Phosphorylation at S68 inhibits ZNF420 binding to the first intron of TP53AIP1 (p53AIP1) gene, thus facilitating TP53 (p53)-mediated expression of TP53AIP1 (Yuan et al. 2012). ATM-mediated phosphorylation of ZNF420 also inhibits ZNF420 interaction with TP53 and the consequent TP53 deacetylation (Tian et al. 2009).
