Small ubiquitin-related modifier sumo
WebFeb 22, 2005 · Importantly, Sp100 and PML are both covalently linked to small ubiquitin-related modifiers (SUMOs). Therefore, we investigated whether SUMO proteins are independent autoantigens in PBC and studied 99 PBC sera samples for reactivity against NDs, PML, and Sp100, as well as against SUMO-2 and SUMO-1 recombinant proteins. WebSep 23, 2004 · Covalent attachment of small proteins to substrates can regulate protein activity in eukaryotes. SUMO, the small ubiquitin-related modifier, can be covalently linked to a broad spectrum of substrates. An understanding of SUMO’s role in plant biology is still in its infancy. In this review, we briefly summarize the enzymology of SUMO conjugation …

WebThe small ubiquitin-like modifier (SUMO) modification alters the subcellular distribution and function of its substrates. Here we show the major role of SUMO during the development … WebAside from ubiquitin, eukaryotes own diverse other proteins which are also involved in the modification of the protein. An additional class of Ub-related-polypeptide tag named small ubiquitin-like modifier (SUMO) is documented with similar functions (Melchior et al. 2000; Johnson et al. 2004). SUMO protein is composed of 100 amino acid residues ...

WebAug 10, 2008 · For human male meiosis, we previously showed that the small ubiquitin-related modifier-1 (SUMO-1) protein localizes to chromatin axes in early pachytene spermatocytes, then to kinetochores as meiosis progresses. Here, we delineate possible functional roles based on subcellular localization for SUMO-1 and SUMO-2/3. METHODS
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.
