Mechanisms of PML degradation. A complex molecular network is involved in PML degradation: these mechanisms include several post-translational modifications that trigger PML ubiquitination and degradation, resulting in the loss of its tumor suppressive activity or antiviral properties. S, SUMOylation; P, phosphorylation.
