Nature Structural & Molecular Biology, Published online: 05 December 2025; doi:10.1038/s41594-025-01717-zRiechmann et al. uncover structural features governing ubiquitin transfer from ubiquitin-activating E1 enzymes UBA1 and UBA6 to specific E2 ubiquitin-conjugating enzymes, revealing a hierarchy of E2 activity with cognate E1s.

During tissue formation, dynamic cell shape changes drive morphogenesis while asymmetric divisions create cellular diversity. We found that the shifts in cell morphology that shape tissues could conco...

Shelford, Burgess, and colleagues present a structural model of the interaction between TACC3 and ch-TOG. They discover Affimers that can inhibit this inte

The BRCC36 isopeptidase complex (BRISC) is a deubiquitylase that stabilizes interferon receptors, driving inflammation. We discovered ‘BRISC molecular glue’ inhibitors (BLUEs) that selectively inactiv...

Inhibition of AMP-activated protein kinase (AMPK) is under increasing investigation for its therapeutic potential in many diseases, including certain cancers. However, existing AMPK-inhibitors availab...

Glycogen synthase (GS) is the rate-limiting enzyme for glycogen production and together with glycogenin (GN) and glycogen branching enzyme (GBE), can generate glycogen particles containing up to 50,00...
