A large number of proteins are modified posttranslationally by the ubiquitin-like protein (Ubl) SUMO. This process, known as sumoylation, regulates the function, localisation and activity of target proteins as part of normal cellular metabolism, e.g., during development, and through the cell cycle, as well as in response to a range of stresses. In order to be effective, the sumoylation pathway itself must also be regulated. This review describes how the SUMOylation process is regulated. In particular, regulation of the SUMO conjugation and deconjugation machinery at the level of transcription and by post-translational modifications is discussed.
