Using dot blot with immunochemical detection to evaluate global changes in SUMO-2/3 conjugation
Small ubiquitin-related modifier-2/3 (SUMO-2/3) is a member of the ubiquitin-like (Ubl) protein family. Conjugation of SUMO-2/3 to target proteins is influenced by various stress conditions and chemical inhibitors.

SUMOylation of Rad52-Rad59 synergistically change the outcome of mitotic recombination [PDF]
Homologous recombination (HR) is essential for maintenance of genome stability through double-strand break (DSB) repair, but at the same time HR can lead to loss of heterozygosity and uncontrolled recombination can be genotoxic.

Modification of CCAAT/Enhancer-binding Protein-β by the Small Ubiquitin-like Modifier (SUMO) Family Members, SUMO-2 and SUMO-3 [PDF]
CCAAT/enhancer-binding protein-beta (C/EBP beta) activator isoforms, C/EBP beta-1 and C/EBP beta-2, differ by only 23 amino acids in the human; however, evidence is accumulating that these transcription factors are functionally distinct. Here we demonstrate that C/EBP beta-1, but not C/EBP beta-2, is conjugated to the small ubiquitin-like modifier ...

Aberrant SUMOylation Restricts the Targetable Cancer Immunopeptidome
Pharmacological SUMOylation inhibition (SUMOi) counteracts tumor immune evasion by unmasking an immunogenic HLA‐I peptide and neoepitope repertoire. By restoring HLA‐I ligand availability through increased antigen processing and presentation, enhanced proteasomal cleavage, and modulated TAP1 peptide affinity, SUMOi boosts tumor immunogenicity ...

Smc5/6: a link between DNA repair and unidirectional replication? [PDF]
Of the three structural maintenance of chromosome (SMC) complexes, two directly regulate chromosome dynamics. The third, Smc5/6, functions mainly in homologous recombination and in completing DNA replication.

SUMO defeats protein aggregates
![Figure][1] Unsumoylated α-synuclein aggregates into fibrils (right), whereas sumoylated α-synuclein doesn't (left). Sumoylation might prevent the protein aggregations that typify Parkinson's disease (PD), [Krumova et al.][2] report.

In this manuscript, protein disulfide isomerase A3 (PDIA3) is identified as a key factor mediating the susceptibility of ferroptosis in GBM. Inhibition of PDIA3 enhances IKE or cystine starvation‐induced ferroptosis in GBM cells by resulting in the accumulation of lipid peroxidation and a reduction in GSH level.

A global S. cerevisiae small ubiquitin‐related modifier (SUMO) system interactome
The small ubiquitin‐related modifier (SUMO) system has been implicated in a number of biological functions, yet the individual components of the SUMO machinery involved in each of these activities were largely unknown.
