Protein modification by SUMO.
Small ubiquitin-related modifier (SUMO) family proteins function by becoming covalently attached to other proteins as post-translational modifications. SUMO modifies many proteins that participate in diverse cellular processes, including transcriptional regulation, nuclear transport, maintenance of genome integrity, and signal transduction. Reversible attachment of SUMO is controlled by an enzy...
متن کاملClassification of protein aggregates.
Comparison of protein aggregates/self-associated species between laboratories and across disciplines is complicated by the imprecise language presently used to describe them. In this commentary, we propose a standardized nomenclature and classification scheme that can be applied to describe all protein aggregates. Five categories are described under which a given aggregate may be independently ...
متن کاملSUMO: a ubiquitin-like protein modifier.
SUMO (Small Ubiquitin-related Modifier) is a small protein that covalently attaches to a lysine residue of another protein in a reversible fashion. SUMO attachment to its substrate proteins causes changes in the localization, activity, or binding partners of the substrate. SUMO has been shown to play a role in a multitude of processes; these include chromosome segregation, cell cycle progressio...
متن کاملSUMO Modification: Wrestling with Protein Conformation
SUMO modification of human thymine-DNA glycosylase facilitates the processing of base excision repair substrates by an unusual mechanism: while leaving the catalytic center unaffected, it induces product release by eliciting a conformational change in the enzyme.
متن کاملRegulation of Protein Function by SUMO Modification
SUMOylation is a post-translational modification that affects a large number of proteins, many of which are nuclear. While the role of SUMOylation is beginning to be elucidated, it is clear that understanding the mechanisms that regulate the process is likely to be important. Control of the levels of SUMOylation is brought about through a balance of conjugating and deconjugating activities, i.e...
