    A cryptic K48 ubiquitin chain binding site on UCH37 is required for its role in proteasomal degradation

    Jiale Du, Sandor Babik ... Eric Strieter
    The proteasomal deubiquitinase UCHL5/UCH37 uses a face distinct from the canonical ubiquitin binding site to engage K48-linked ubiquitin chains and catalyze chain debranching.

    Effector membrane translocation biosensors reveal G protein and βarrestin coupling profiles of 100 therapeutically relevant GPCRs

    Charlotte Avet, Arturo Mancini ... Michel Bouvier
    Development, validation, and use of an effector membrane translocation biosensor platform reveals G protein coupling selectivity signatures for 100 GPCRs that range from remarkable selectivity to full promiscuity toward the different G protein subtypes.

    Glutathione binding to the plant AtAtm3 transporter and implications for the conformational coupling of ABC transporters

    Chengcheng Fan, Douglas C Rees
    Multiple cryo-electron microscopy structures of a plant ABC transporter exporting glutathione derivatives captured a closed conformation proposed to enforce the export directionality, while a complex central to the coupling mechanism containing both glutathione and closed nucleotide binding domains remains elusive.

    Co-aggregation and secondary nucleation in the life cycle of human prolactin/galanin functional amyloids

    Debdeep Chatterjee, Reeba S Jacob ... Samir K Maji
    Co-aggregation, amyloid formation, and unidirectional cross-seeding of prolactin and galanin for their efficient storage in secretory granules of pituitary and subsequent functional hormone release.

    Agl24 is an ancient archaeal homolog of the eukaryotic N-glycan chitobiose synthesis enzymes

    Benjamin H Meyer, Panagiotis S Adam ... Helge C Dorfmueller
    The crenarchaeon Sulfolobus synthesizes the N-glycan core in the identical way as all Eukaryotes, which strengthens the hypothesis that the eukaryotic N-glycosylation is acquired from an ancient archaeon during eukaryogenesis.

    GFPT2/GFAT2 and AMDHD2 act in tandem to control the hexosamine pathway

    Virginia Kroef, Sabine Ruegenberg ... Martin Sebastian Denzel
    AMDHD2 restricts the activity of the essential hexosamine pathway in mouse embryonic stem cells where GFPT2/GFAT2 instead of the common paralog GFPT1/GFAT1 controls metabolite entry.
