    Structural basis for anion conduction in the calcium-activated chloride channel TMEM16A

    Cristina Paulino, Yvonne Neldner ... Raimund Dutzler
    Single-particle cryo-EM and electrophysiology studies of the chloride channel TMEM16A reveals the structural basis for anion conduction and uncover its relationship to lipid scramblases of the same family.

    A selectivity filter at the intracellular end of the acid-sensing ion channel pore

    Timothy Lynagh, Emelie Flood ... Stephan A Pless
    Sodium selectivity of acid-sensing ion channels is mediated by negatively charged side chains and not by a size-exclusion mechanism.

    Helical jackknives control the gates of the double-pore K+ uptake system KtrAB

    Marina Diskowski, Ahmad Reza Mehdipour ... Inga Hänelt
    The K(+) uptake system KtrAB is controlled by an allosteric mechanism entirely new for membrane channels, which operates the channel gate over a 35 Å distance.

    The force-sensing peptide VemP employs extreme compaction and secondary structure formation to induce ribosomal stalling

    Ting Su, Jingdong Cheng ... Roland Beckmann
    The structure of the VemP-stalled ribosome reveals a helix-double turn-helix conformation of the nascent chain within the ribosomal tunnel, illustrating how secondary structure formation directly at the peptidyltransferase center of the ribosome can induce translational arrest.

    CTCF and cohesin regulate chromatin loop stability with distinct dynamics

    Anders S Hansen, Iryna Pustova ... Xavier Darzacq
    Single-molecule imaging of CTCF and cohesin in live cells suggests that chromatin loops are dynamic structures that frequently form and fall apart.

    The RNF168 paralog RNF169 defines a new class of ubiquitylated histone reader involved in the response to DNA damage

    Julianne Kitevski-LeBlanc, Amélie Fradet-Turcotte ... Lewis E Kay
    A structural model of the dynamic complex comprising the histone reader RNF169 bound to an ubiquitylated nucleosome core particle reveals a three-pronged binding mechanism, which provides specificity for the recognition of DNA double-strand break sites.
