RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]
Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,

SUMO (small ubiquitin-related modifier) family proteins are not only structurally but also mechanistically related to ubiquitin in that they are posttranslationally attached to other proteins. As ubiquitin, SUMO is covalently linked to its substrates via amide (isopeptide) bonds formed between its C-terminal glycine residue and the epsilon-amino group ...

SUMOylation regulates LKB1 localization and its oncogenic activity in liver cancer [PDF]
BACKGROUND: Even though liver kinase B1 (LKB1) is usually described as a tumor suppressor in a wide variety of tissues, it has been shown that LKB1 aberrant expression is associated with bad prognosis in Hepatocellular Carcinoma (HCC).

USE OF SUMO-EXPRESSION SYSTEM AND SUMO-PROTEASE FOR PRODUCTION OF ACTIVE INTERFERON α-2b [PDF]
Recombinant proteins production in prokaryotic expression systems is often complicated by need of native, N-terminal formylmethionine free molecule extraction, refolding, and processing.

Functional reconstitution of a tunable E3-dependent sumoylation pathway in Escherichia coli. [PDF]
SUMO (small ubiquitin-related modifier) is a reversible post-translational protein modifier that alters the localization, activity, or stability of proteins to which it is attached.

An influenza virus-triggered SUMO switch orchestrates co-opted endogenous retroviruses to stimulate host antiviral immunity [PDF]
Dynamic small ubiquitin-like modifier (SUMO) linkages to diverse cellular protein groups are critical to orchestrate resolution of stresses such as genome damage, hypoxia, or proteotoxicity.

SUMO: of branched proteins and nuclear bodies [PDF]
SUMO belongs to a growing number of ubiquitin-like proteins that covalently modify their target proteins. Although some evidence supports a role of SUMO modification in regulating protein stability, most studied examples support a model by which SUMO alters the interaction properties of its targets, often affecting their subcellular localization ...

A Photo-Crosslinking Approach to Identify Class II SUMO-1 Binders
The small ubiquitin-like modifier (SUMO) is involved in various cellular processes and mediates known non-covalent protein-protein interactions by three distinct binding surfaces, whose interactions are termed class I to class III.

The role of Schizosaccharomyces pombe SUMO ligases in genome stability [PDF]
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 ...

SUMOylation inhibits FOXM1 activity and delays mitotic transition [PDF]
The forkhead box transcription factor FOXM1 is an essential effector of G2/M-phase transition, mitosis and the DNA damage response. As such, it is frequently deregulated during tumorigenesis. Here we report that FOXM1 is dynamically modified by SUMO1 but
