1 KAP1 reduction markedly enhanced the induction of p21, a product of the p53 target gene, after treatment with actinomycin D or gamma-irradiation, but not with camptothecin. Dactinomycin tumor protein p53 Homo sapiens
2 Treatment with actinomycin D, but not with camptothecin, augmented the interaction of p53 with Mdm2 and KAP1. Dactinomycin tumor protein p53 Homo sapiens
3 Thus, the reduction of KAP1 levels promotes p53-dependent p21 induction and inhibits cell proliferation in actinomycin D-treated cells. Dactinomycin tumor protein p53 Homo sapiens
