    Kinetics of initiating polypeptide elongation in an IRES-dependent system

    Haibo Zhang, Martin Y Ng ... Barry S Cooperman
    The retarding effect of a ribosome-bound internal ribosome entry site on eukaryotic protein synthesis is largely overcome following translocation of tripeptidyl-tRNA.

    A filter at the entrance of the Golgi that selects vesicles according to size and bulk lipid composition

    Maud Magdeleine, Romain Gautier ... Bruno Antonny
    The golgin GMAP-210 captures vesicles at the cis Golgi by merely recognizing the high curvature and lipid unsaturation level of transport vesicles.

    Nonenzymatic copying of RNA templates containing all four letters is catalyzed by activated oligonucleotides

    Noam Prywes, J Craig Blain ... Jack W Szostak
    Nonenzymatic polymerization can copy templates containing all four RNA monomers, a prerequisite for the transition to the RNA world.

    Small molecule proteostasis regulators that reprogram the ER to reduce extracellular protein aggregation

    Lars Plate, Christina B Cooley ... Jeffery W Kelly
    Small molecule proteostasis regulators that activate the unfolded protein response transcription factor ATF6 reduce the secretion of amyloid disease-associated proteins.

    Mia40 is a trans-site receptor that drives protein import into the mitochondrial intermembrane space by hydrophobic substrate binding

    Valentina Peleh, Emmanuelle Cordat, Johannes M Herrmann
    The import of proteins into the intermembrane space of mitochondria is driven by binding to the trans-site receptor Mia40 and not by the oxidation of cysteine residues.

    The Lamin B receptor is essential for cholesterol synthesis and perturbed by disease-causing mutations

    Pei-Ling Tsai, Chenguang Zhao ... Christian Schlieker
    Lamin B receptor may provide a long-sought model system enabling unprecedented studies of protein quality control in the nuclear envelope of mammalian cells.

    A cytoplasmic peptidoglycan amidase homologue controls mycobacterial cell wall synthesis

    Cara C Boutte, Christina E Baer ... Eric J Rubin
    Cell wall biosynthesis in mycobacteria is regulated by an unusual post-translational regulatory system that contributes to antibiotic tolerance during stress.

    Obligate coupling of CFTR pore opening to tight nucleotide-binding domain dimerization

    Csaba Mihályi, Beáta Töröcsik, László Csanády
    Coupling of CFTR pore opening to nucleotide binding domain dimerization does not depend on ATP binding, but is an inherent property of the channel protein and likely other ABC transporters.

    Complementary shifts in photoreceptor spectral tuning unlock the full adaptive potential of ultraviolet vision in birds

    Matthew B Toomey, Olle Lind ... Joseph C Corbo
    Birds that see ultraviolet light tune the sensitivity of their short-wavelength photoreceptors with colored filters to maximize the number of colors they can see.
