In molecular biology, SUMO (Small Ubiquitin-like Modifier) proteins are a family of small proteins that are covalently attached to and detached from other proteins in cells to modify their function. This process is called SUMOylation (sometimes written sumoylation). SUMOylation is a post-translational modification … See more SUMO modification of proteins has many functions. Among the most frequent and best studied are protein stability, nuclear-cytosolic transport, and transcriptional regulation. Typically, only a small fraction of a given protein is … See more SUMO proteins are small; most are around 100 amino acids in length and 12 kDa in mass. The exact length and mass varies between SUMO … See more SUMO attachment to its target is similar to that of ubiquitin (as it is for the other ubiquitin-like proteins such as NEDD 8). The SUMO precursor has some extra amino acids that need to be removed, therefore a C-terminal peptide is cleaved from the SUMO … See more Recombinant proteins expressed in E. coli may fail to fold properly, instead forming aggregates and precipitating as inclusion bodies. This insolubility may be due to the presence of codons read inefficiently by E. coli, differences in eukaryotic and prokaryotic … See more Most SUMO-modified proteins contain the tetrapeptide consensus motif Ψ-K-x-D/E where Ψ is a hydrophobic residue, K is the lysine conjugated to SUMO, x is any amino acid (aa), D or E is an acidic residue. Substrate specificity appears to be derived directly from Ubc9 … See more SUMO can be removed from its substrate, which is called deSUMOylation. Specific proteases mediate this procedure (SENP in human or Ulp1 … See more • SUMO1 • SUMO2 • SUMO3 • SUMO4 See more WebSUMOylation by generating mature small ubiquitin-related modifiers (SUMO) for protein conjugation (endopeptidase activity)andremovingconjugatedSUMOfromtargets(isopep …
