    Gene activation by a CRISPR-assisted trans enhancer

    Xinhui Xu, Jinliang Gao ... Jinke Wang
    Both exogenous and endogenous genes can be highly activated in cells by a new dCas9-based activator, CRISPR-assisted trans enhancer, that can be used to activate genes for biomedical applications.

    A bacterial riboswitch class for the thiamin precursor HMP-PP employs a terminator-embedded aptamer

    Ruben M Atilho, Gayan Mirihana Arachchilage ... Ronald R Breaker
    Many bacteria use a tiny riboswitch aptamer to sense the thiamin precursor HMP-PP to regulate the production of another thiamin precursor HET-P to efficiently biosynthesize this essential coenzyme.

    Targeted degradation of aberrant tau in frontotemporal dementia patient-derived neuronal cell models

    M Catarina Silva, Fleur M Ferguson ... Stephen J Haggarty
    A new Cereblon-recruiting bifunctional tau ligand, QC-01-175, promotes aberrant tau degradation and rescue of stress vulnerability in human neuronal cell models of tauopathy.

    Cryo-EM reveals distinct conformations of E. coli ATP synthase on exposure to ATP

    Meghna Sobti, Robert Ishmukhametov ... Alastair G Stewart
    Cryo-EM studies reveal that incubation with ATP produces conformational intermediates of E. coli ATP synthase, in which the ε subunit is no longer in its autoinhibitory conformation.

    Intramolecular domain dynamics regulate synaptic MAGUK protein interactions

    Nils Rademacher, Benno Kuropka ... Sarah A Shoichet
    Binding of ligands to PSD-95 PDZ domains induces a conformational change within the C-terminal domain module that enables differential binding to synaptic interactors.
