In addition to being structurally related, the protein modifiers ubiquitin and SUMO (small ubiquitin-related modifier), share a multitude of functional interrelations. These include the targeting of the same attachment sites in certain substrates, and SUMO-dependent ubiquitylation in others. Notably, several cellular processes, including the targeting of repair machinery to DNA damage sites, require the sequential sumoylation and ubiquitylation of distinct substrates. Some proteins promote both modifications. By contrast, the activity of some enzymes that control either sumoylation or ubiquitylation is regulated by the respective other modification. In this review, we summarize recent findings regarding intersections between SUMO and ubiquitin that influence genome stability and cell growth and which are relevant in pathogen resistance and cancer treatment.
