SUMO-interacting Motif (SIM): Proteins and Enzymes

Small Ubiquitin-like Modifiers (SUMOs) are a family of small, related proteins that are enzymatically attached to target proteins by a process termed SUMOylation. This post-translational modification regulates many cellular processes including DNA transcription and repair, cell cycle progression, protein intracellular trafficking, and nuclear receptor activities. SUMO binding and/or interaction with proteins is mediated by short amino acid consensus sequences termed SUMO-interacting motifs ...
