    MutSα maintains the mismatch repair capability by inhibiting PCNA unloading

    Yoshitaka Kawasoe, Toshiki Tsurimoto ... Tatsuro S Takahashi
    Biochemical analysis in Xenopus egg extracts reveals that the MutSα mismatch sensor retains the DNA-bound replication clamp to maintain a post-replicative temporal window permissive to strand-specific repair of mismatches.

    Architecture and RNA binding of the human negative elongation factor

    Seychelle M Vos, David Pöllmann ... Patrick Cramer
    The structural architecture of the 4-subunit, RNA-binding human negative elongation factor NELF is derived by a combination of X-ray crystallography and protein crosslinking.

    Time-resolved studies define the nature of toxic IAPP intermediates, providing insight for anti-amyloidosis therapeutics

    Andisheh Abedini, Annette Plesner ... Ann Marie Schmidt
    Toxic IAPP intermediates have some molecular features that are similar to, and others that are distinct from, toxic species reported for other amyloidogenic polypeptides.

    Golgi self-correction generates bioequivalent glycans to preserve cellular homeostasis

    Haik Mkhikian, Christie-Lynn Mortales ... Michael Demetriou
    Structurally dissimilar N-glycans can be functionally equivalent, and are produced via a self-correcting feature of the Golgi.

    Adenosine diphosphate restricts the protein remodeling activity of the Hsp104 chaperone to Hsp70 assisted disaggregation

    Agnieszka Kłosowska, Tomasz Chamera, Krzysztof Liberek
    Hsp70 chaperone provides Hsp104 with high efficiency in disaggregation and specificity towards aggregated substrates at the, otherwise limiting, cellular concentrations of adenine nucleotides.

    The functional O-mannose glycan on α-dystroglycan contains a phospho-ribitol primed for matriglycan addition

    Jeremy L Praissman, Tobias Willer ... Lance Wells
    Disruption of the LG domain-binding phospho-ribitol-containing O-mannose structures on α-dystroglycan results in congenital muscular dystrophy.
