Small ubiquitin-related modifier sumo
WebA key mechanism is the posttranslational modification of Tfs via conjugation with small ubiquitin-related modifier (SUMO) proteins. SUMO modification primarily affects proteins of the transcriptional machinery, with effects on DNA binding activity, subcellular localization of Tfs, interaction of Tfs with coregulators, and chromatin structure [64]. 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 of the Caenorhabditis elegans reproductive system. smo-1 deletion mutants develop into sterile adults with abnormal somatic gonad, germ line, and vulva.

WebThe Small Ubiquitin-related Modifier, SUMO-1, [1] [2] is a ubiquitin-like family member that is conjugated to its substrates through three discrete enzymatic steps (see the figure on the right): activation, involving the E1 enzyme ( SAE1 / SAE2 ); [3] conjugation, involving the E2 enzyme ( UBE2I ); [4] [5] substrate modification, through the … WebNov 6, 2024 · This gene is a member of the SUMO gene family. This family of genes encode small ubiquitin-related modifiers that are attached to proteins and control the target proteins' subcellular localization, stability, or activity. The protein described in this record is located in the cytoplasm and specifically modifies IKBA, leading to negative regulation of …
WebMar 15, 2012 · SUMO (small ubiquitin-related modifier) conjugation is a reversible three-step process of protein post-translational modifications mediating protein-protein interactions, subcellular compartmentalization and regulation of transcriptional events. Among divergent transcription factors regulated by SUMOylation and deSUMOylation, the … WebSep 29, 2024 · Small ubiquitin-related modifier (SUMO) is one such modifier. Therefore, ubiquitination and sumoylation are two post-translational modifications. Ubiquitination marks proteins for degradation. In contrast, sumoylation is not used to mark proteins for degradation. Both modifications regulate protein localization and activity.
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 WebApr 11, 2024 · The small ubiquitin modifier-1 (SUMO-1) belongs to the family of ubiquitin-related proteins and is involved in the modulation of protein–protein interactions, as well …
