Cryo-EM structures reveal the molecular mechanism of SUMO E1–E2 thioester transfer
Nature Structural & Molecular Biology, Published online: 25 September 2025; doi:10.1038/s41594-025-01681-8This study reveals how human small ubiquitin-like modifier (SUMO) E1 recruits its E2 partner UBC9 and transfers SUMO1 through large structural changes, uncovering key mechanisms that ensure specificity and fidelity in SUMOylation, an essential protein modification pathway.

🧵"So this is how liberty dies..." Trump’s first 3 weeks have been a relentless flood of actions. It's incredibly hard to keep up. I’ve gone through 69 actions & mapped out the pattern - showing how they fall within 5 broad domains consistent with authoritarian states 1/9
This is a venn diagram showing how 69 Trump actions map onto domains covering: undermining democratic institutions; suppressing dissent and media; dismantling social protections; attacking science and education; destabilising the global order.

Tumor-induced metabolic immunosuppression: Mechanisms and therapeutic targets
This review explores how metabolic reprogramming in cancer and immune cells impacts antitumor responses. It highlights how altered metabolism affects immune function and cancer progression, discusses therapeutic strategies targeting these pathways, and examines innovative combinations of immunotherapy, cellular therapies, and metabolic interventions to enhance treatment efficacy.

ULP-2 is a conserved SUMO protease required for embryonic development in #Celegans, but what does it do? This study shows that ULP-2 controls germline development by regulating #SUMOylation levels (and so activity) of H3K4me3 reader SET-26 🧪 @plosbiology.org plos.io/403ixQ5
Top left:  Representative images of the isolated germlines of WT and F2 ulp-2(tv380) animals; the germline zones and sperm are indicated. Scale bar = 30 μm. Insets below the images show magnification of the proximal gonad and sperm. Bottom left: Representative images of UNC-119::GFP localization in WT and F2 ulp-2(tv380) animals. White line marks the proximal gonad, most proximal oocyte (oo) and spermatheca (sp). Right: Model for SET-26 functional dependence on sumoylation. In homeostasis, SET-26 and its interactors bind H3K4me3 marks to regulate gene expression. Unbalanced sumoylation of SET-26 disrupts its reader function by decreasing its binding to H3K4me3 marks. Consequently, germline transcription is perturbed.
