This study shows Faf2/Ubx2 enhances p97/Cdc48 segregase activity by remodeling its substrate recognition module and priming its motor engagement, enabling efficient substrate processing.

This paper develops a conformation-specific antibody, K27-IgG, to detect K27-linked polyubiquitin and identifies DNAJB1 as a reader and UBE2Q1 as a writer for this ubiquitin chain type.

The paper determines cryo-EM structures of IMiDs in full CRL4CRBN complexes, revealing a cryptic interfacial pocket that enhances IMiD efficacy and neosubstrate specificity.

This study determines the structural mechanism of HECT-type E3 ligase Ufd4 in catalyzing K29/K48-branched polyubiquitination by capturing structural snapshots of Ub transfer cascades.

This study determines the cryo-EM structures of RNF168/UbcH5c-Ub/nucleosome complexes to elucidate the mechanism of H2A K13/K15 site-specific ubiquitination.

The paper determines the crystal structure of phytoplasma effector SAP05 bound to plant Rpn10, revealing a ubiquitin-independent degradation mechanism and conserved interaction patterns across species.
