Here, our study shows that this inhibition can be overcome by 14-3-3gamma and Chk1. 14-3-3gamma was identified as an MDMX-associated protein via an immuno-affinity purification-coupled mass spectrometry. Consistently, 14-3-3gamma directly interacted with MDMX in vitro, and this interaction was stimulated by MDMX phosphorylation in vitro and in cells. Interestingly, in response to UV irradiation, the wild-type, but not the kinase-dead mutant, Chk1 phosphorylated MDMX at serine 367, enhanced the 14-3-3gamma-MDMX binding and the cytoplasmic retaining of MDMX. The Chk1 specific inhibitor UCN-01 repressed all of these effects. Moreover, overexpression of 14-3-3gamma, but not its mutant K50E, which did not bind to MDMX, suppressed MDMX-enhanced p53 ubiquitination, leading to p53 stabilization and activation. Finally, ablation of 14-3-3gamma by siRNA reduced UV-induced p53 level and G1 arrest. Thus, these results demonstrate 14-3-3gamma and Chk1 as two novel regulators of MDMX in response to UV irradiation."xsd:string |
