    Near-atomic structures of the BBSome reveal the basis for BBSome activation and binding to GPCR cargoes

    Shuang Yang et al.
    Membrane recruitment of BBSome is coupled to a conformational change, and interaction of the BBSome with GPCR cargoes depends on the GPCRs releasing their amphipathic helix 8 from the membrane.

    Moyamoya disease factor RNF213 is a giant E3 ligase with a dynein-like core and a distinct ubiquitin-transfer mechanism

    Juraj Ahel et al.
    RNF213 is a giant E3 ligase with a dynein-like core and a unique ubiquitination mechanism that proceeds in a RING-independent manner and is linked with the Moyamoya disease.

    The His-Gly motif of acid-sensing ion channels resides in a reentrant ‘loop’ implicated in gating and ion selectivity

    Nate Yoder, Eric Gouaux
    The amino terminus of acid-sensing ion channel 1a forms a reentrant 'loop' that frames the lower pore and harbors a conserved 'His-Gly' motif implicated in gating and ion selectivity mechanisms.

    Intracellular calcium leak lowers glucose storage in human muscle, promoting hyperglycemia and diabetes

    Eshwar R Tammineni et al.
    Calcium-driven protein changes, causing glycogenolysis, poor synthesis, and diminished content of glycogen, along with diminished glucose transporters, lead to hyperglycemia in patients prone to calcium leaks from intracellular muscle stores.

    mRNA stem-loops can pause the ribosome by hindering A-site tRNA binding

    Chen Bao et al.
    By sterically hindering tRNA binding and inhibiting translation elongation, mRNA stem-loops can modulate gene expression.

    Divergent Cl- and H+ pathways underlie transport coupling and gating in CLC exchangers and channels

    Lilia Leisle et al.
    Combined simulations and electrophysiological experiments show that the CLC channels and exchangers form physically distinct and evolutionarily conserved pathways through which Cl- and H+ ions move when crossing biological membranes.

    Mechanisms of nucleotide selection by telomerase

    Matthew A Schaich et al.
    The roles of key telomerase active site residues were elucidated to determine how telomerase selects the correct from the incorrect nucleotide to maintain telomere integrity.
