ULP-1, ubiquitin-like protein-specific protease 1, initially processes Smt3 and also acts as adeconjugating enzyme for Smt3 [Saccharomyces cerevisiae (Baker's yeast)]. Covalent modification of cellular proteins by theubiquitin-like modifier SUMO (small ubiquitin-like modifier) regulates various cellular processes, such as nuclear transport, signaltransduction, stress responses and cell cycle progression. But, in contrast to ubiquination, sumoylation does not tag proteins fordegradation by the 26S proteasome, but rather seems to enhance stability or modulate their subcellular compartmentalization. Oncecovalently attached to cellular targets, SUMO regulates protein:protein and protein:DNA interactions, as well as localization andstability of the target protein. Sumoylation occurs in most eukaryotic systems, and SUMO is highly conserved from yeast to humans.Where invertebrates have only a single SUMO gene termed SMT3, three members of the SUMO family have been identified invertebrates: SUMO-1 and the close homologues SUMO-2 and SUMO-3. Three distinct steps can be distinguished in the SUMOmodification pathway: 1) activation of SUMO, 2) transfer of SUMO to the conjugating enzyme, and 3) substrate modification. SinceSUMO is synthesized as a precursor protein, a maturation step precedes the activation reaction. In yeast, C-terminal processing of theSUMO precursor is mediated by the processing protease Ulp1, which has an additional role in the deconjugation of SUMO-modifiedsubstrates. Mature SUMO is activated by SUMO-activating enzyme, an E1-like heterodimeric protein complex composed of Uba2 andAos1. Ulp1 function has provided evidence that SUMO modification in yeast, as has been suspected for vertebrates, plays animportant role in nucleocytoplasmic trafficking.
