Homologous Recombination: To Fork and Beyond [PDF]
Accurate completion of genome duplication is threatened by multiple factors that hamper the advance and stability of the replication forks. Cells need to tolerate many of these blocking lesions to timely complete DNA replication, postponing their repair ...

SUMO: regulating the regulator
Post-translational modifiers of the SUMO (Small Ubiquitin-related Modifier) family have emerged as key regulators of protein function and fate. While the past few years have seen an enormous increase in knowledge on SUMO enzymes, substrates, and ...

Site-specific identification and quantitation of endogenous SUMO modifications under native conditions. [PDF]
Small ubiquitin-like modifier (SUMO) modification regulates numerous cellular processes. Unlike ubiquitin, detection of endogenous SUMOylated proteins is limited by the lack of naturally occurring protease sites in the C-terminal tail of SUMO proteins ...

Insights Into the Allosteric Inhibition of the SUMO E2 Enzyme Ubc9 [PDF]
AbstractConjugation of the small ubiquitin‐like modifier (SUMO) to protein substrates is an important disease‐associated posttranslational modification, although few inhibitors of this process are known. Herein, we report the discovery of an allosteric small‐molecule binding site on Ubc9, the sole SUMO E2 enzyme.

Molecular Characterization and Functional Localization of a Novel SUMOylation Gene in Oryza sativa
Small ubiquitin-related modifier (SUMO) regulates the cellular function of diverse proteins through post-translational modifications. The current study defined a new homolog of SUMO genes in the rice genome and named it OsSUMO7. Putative protein analysis

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).

Site-specific inhibition of the small ubiquitin-like modifier (SUMO)-conjugating enzyme Ubc9 selectively impairs SUMO chain formation [PDF]
Posttranslational modifications by small ubiquitin-like modifiers (SUMOs) regulate many cellular processes, including genome integrity, gene expression, and ribosome biogenesis. The E2-conjugating enzyme Ubc9 catalyzes the conjugation of SUMOs to ϵ-amino groups of lysine residues in target proteins.

Global SUMO proteome responses guide gene regulation, mRNA biogenesis, and plant stress responses
Small-ubiquitin-like MOdifier (SUMO) is a key regulator of abiotic stress, disease resistance and development in plants. The identification of >350 plant SUMO targets has revealed many processes modulated by SUMO and potential consequences of SUMO on ...

Structural modeling and functional analysis of the essential ribosomal processing protease Prp from Staphylococcus aureus [PDF]
In Firmicutes and related bacteria, ribosomal large subunit protein L27 is encoded with a conserved N-terminal extension that is removed to expose residues critical for ribosome function. Bacteria encoding L27 with this N-terminal extension also encode a
