Figure 1From: The role of PML ubiquitination in human malignanciesSummary of the PML ubiquitination/degradation pathways. These pathways are activated by extracellular or intracellular stimuli, primed by distinct PML posttranslational modifications, mediated by indicated E3 ligases, and perturbed in different types of human cancers. Unidentified E3 ligases are shown by question marks.Back to article page
