A role for SUMO modification in transcriptional repression and activation [PDF]
Since the discovery of the SUMO (small ubiquitin-like modifier) family of proteins just over a decade ago, a plethora of substrates have been uncovered including many regulators of transcription.

The Role of the Small Ubiquitin-Related Modifier (SUMO) Pathway in Prostate Cancer
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.

Small ubiquitin‐like modifier (SUMO) conjugation, or SUMOylation, is a reversible post‐translational modification that is important for regulation of many cellular processes including cell division cycle in the eukaryotic kingdom. However, only a portion

The ubiquitin-proteasome pathway in Huntington's disease. [PDF]
The accumulation of mutant protein is a common feature of neurodegenerative disease. In Huntington's disease, a polyglutamine expansion in the huntingtin protein triggers neuronal toxicity.

SUMO modification of the ubiquitin-conjugating enzyme E2-25K
Post-translational modification with small ubiquitin-related modifier (SUMO) alters the function of many proteins, but the molecular mechanisms and consequences of this modification are still poorly defined. During a screen for novel SUMO1 targets, we identified the ubiquitin-conjugating enzyme E2-25K (Hip2).

Purification of SUMO Conjugating Enzymes and Kinetic Analysis of Substrate Conjugation [PDF]
SUMO conjugation to protein substrates requires the concerted action of a dedicated E2 ubiquitin conjugation enzyme (Ubc9) and associated E3 ligases. Although Ubc9 can directly recognize and modify substrate lysine residues that occur within a consensus site for SUMO modification, E3 ligases can redirect specificity and enhance conjugation rates during

N-terminal α-amino SUMOylation of cofilin-1 is critical for its regulation of actin depolymerization
Small ubiquitin-like modifier (SUMO) typically conjugates to target proteins through isopeptide linkage to the ε-amino group of lysine residues. This posttranslational modification (PTM) plays pivotal roles in modulating protein function.

Ubiquitination accomplished: E1 and E2 enzymes were not necessary [PDF]
Qiu et al. (2016) show that a mono-ADP-ribosyltransferase, SdeA, from Legionella pneumophila catalyzes ADP-ribosylation of ubiquitin, allowing SdeA to modify substrate with ubiquitin in the absence of E1 and E2 ...

Characterization of SUMO-conjugating enzyme mutants in Schizosaccharomyces pombe identifies a dominant-negative allele that severely reduces SUMO conjugation [PDF]
The phenotypes of mutants defective in the Schizosaccharomyces pombe SUMO (small, ubiquitin-like modifier)-conjugating enzyme Hus5 (the homologue of Ubc9) show that it is required for recovery from S-phase arrest. Unlike the case with ubiquitination, where ligases are required, SUMO-conjugating enzymes are sufficient for substrate recognition and ...
