The study showed that FL118 inhibits p53 polyubiquitination and monoubiquitination through the oncogenic Mdm2 - MdmX E3 complex, while stimulating Mdm2 - mediated MdmX ubiquitination — by changing the target specificity of Mdm2 - MdmX E3 complex from p53 to MdmX.

We can tightly control the expression of ubiquitin using experimental induction, which is ideal for studying a highly dynamic process such as ubiquitination.

Given their in vivo role in pathogenicity, and based on the yeast two - hybrid interaction data, these results point to the importance of these pathogen proteins in modulating host ubiquitination pathways, phagosomal escape, and actin - cytoskeleton rearrangement processes.
