Protein post-translational modification by the small ubiquitin-like modifier (SUMO), or SUMOylation, can regulate the stability, subcellular localization or interactome of a protein substrate with key consequences for cellular processes including the Epithelial-Mesenchymal Transition (EMT). The secreted protein Transforming Growth Factor beta (TGFβ) is a potent inducer of EMT in development and homeostasis. Importantly, the ability of TGFβ to induce EMT has been implicated in promoting cancer invasion and metastasis, resistance to chemo/radio therapy, and maintenance of cancer stem cells. Interestingly, TGFβ-induced EMT and the SUMO system intersect with important implications for cancer formation and progression, and novel therapeutics identification.

To maintain genome stability, proliferating cells must enact a program of telomere maintenance. While most tumors maintain telomeres through the action of telomerase, a subset of tumors utilize a DNA-templated process termed Alternative Lengthening of Telomeres or ALT. ALT is associated with mutations in the ATRX/DAXX/H3.

SUMOylation involves covalent attachment of small ubiquitin-like modifier (SUMO) proteins to specific lysine residues on target proteins and regulates various aspects of their function. Sentrin-specific proteases (SENPs) are key players in both the conjugation reaction of SUMO proteins to their targets and the subsequent deconjugation of SUMO-conjugated substrates. Here, we provide the first comprehensive prenatal description of a lethal syndrome linked to a novel homozygous stop-gain variant in SENP7 c.

Effector proteins secreted via the type III secretion system (T3SS) of nitrogen-fixing rhizobia are key determinants of symbiotic compatibility in legumes. Previous report revealed that the T3SS of Bradyrhizobium sp. DOA9 plays negative effects on Arachis hypogaea symbiosis.

Herein, SUMO-LUMO inversion (SLI) radicals - were designed by the combination of the tris(2,4,6-trichlorophenyl)methyl (TTM) radical and pyridinium derivatives (electron-withdrawing groups) for the first time. The energy of the LUMO lies below that of the SUMO, which deviated from the Aufbau principle as an alternative electronic configuration beyond the well-established SOMO-HOMO inversed system. Thus, for SLI radicals, the injection of one extra electron preferred to occupy the LUMO rather than the SUMO, giving diradicals, one of which had been fully confirmed by single crystal analysis, VT-NMR and VT-EPR experiments, as well as DFT calculations.

Background: The modification of protein substrates by small ubiquitin-related modifier (SUMO) plays a vital role in plants subjected to biotic and abiotic stresses. However, its role in the stress responses of Brassica plants remains poorly understood.

Results: A genome-wide analysis revealed the presence of 30 SUMOylation genes in the Caixin genome.
