Historical Background
Posttranslational modification of eukaryotic cellular proteins with small ubiquitin-like modifier (SUMO) proteins, i.e., sumoylation (GO: 0016925), has a variety of functional effects, including the modification of protein structure and the regulation of the intracellular or intranuclear localization, among others. In this manner, sumoylation contributes to the regulation of signal transduction pathways and gene expression systems related to the cell cycle control, apoptosis, cell differentiation, and the stress response, among others (Saitoh and Hinchey 2000; Johnson 2004; Schulman and Harper 2009).
Ubiquitin and ubiquitin-like protein conjugation requires the sequential action of three enzymatic activities (namely E1, E2, and E3) that are conserved...
