    A physicochemical perspective of aging from single-cell analysis of pH, macromolecular and organellar crowding in yeast

    Sara N Mouton, David J Thaller ... Liesbeth M Veenhoff
    In mitotically aging yeast cells, the cytosol acidifies, the distances between the organellar membranes decrease dramatically, but crowding on the scale of the average size protein is relatively stable.

    POMK regulates dystroglycan function via LARGE1-mediated elongation of matriglycan

    Ameya S Walimbe, Hidehiko Okuma ... Kevin P Campbell
    Protein O-Mannose Kinase enables Like-acetyl-glucosaminyltransferase 1 to elongate matriglycan on α-dystroglycan, thereby allowing matriglycan to function as a scaffold for extracellular matrix proteins and prevent muscular dystrophy.

    Genome-wide effects of the antimicrobial peptide apidaecin on translation termination in bacteria

    Kyle Mangano, Tanja Florin ... Nora Vázquez-Laslop
    Inhibition of bacterial protein synthesis by an antimicrobial peptide apidaecin triggers translation arrest at the stop codons, ribosome queuing and pervasive stop codon readthrough.

    Breakage of the oligomeric CaMKII hub by the regulatory segment of the kinase

    Deepti Karandur, Moitrayee Bhattacharyya ... John Kuriyan
    Activation and autophosphorylation of CaMKII releases the regulatory segment, which can then bind to and destabilize the hub assembly by trapping large fluctuations in the hub architecture.

    Serine phosphorylation regulates the P-type potassium pump KdpFABC

    Marie E Sweet, Xihui Zhang ... David L Stokes
    Phosphorylation of a highly conserved serine residue is a physiological response of Escerichia coli to environmental potassium levels that inhibits transport by KdpFABC to maintain cellular homeostasis.

    Alkylative damage of mRNA leads to ribosome stalling and rescue by trans translation in bacteria

    Erica N Thomas, Kyusik Q Kim ... Hani S Zaher
    Alkylation stress modify mRNAs and results in translation arrest, which activates the ribosome-rescue pathway of trans translation in bacteria.

    Phosphatidylinositol 3-phosphate and Hsp70 protect Plasmodium falciparum from heat-induced cell death

    Kuan-Yi Lu, Charisse Flerida A Pasaje ... Emily Derbyshire
    Phosphatidylinositol 3-phosphate interacts with PfHsp70-1 and stabilizes the Plasmodium digestive vacuole under febrile temperatures.

    Optogenetic activation of heterotrimeric G-proteins by LOV2GIVe, a rationally engineered modular protein

    Mikel Garcia-Marcos, Kshitij Parag-Sharma ... Lien T Nguyen
    LOV2GIVe allows to activate Gi proteins non-invasively with innocuous blue light based on a design principle unrelated to light-activated GPCRs (metazoan opsins), thereby expanding the range of potential experimental applications.

    An ER translocon for multi-pass membrane protein biogenesis

    Philip T McGilvray, S Andrei Anghel ... Robert J Keenan
    A set of ER-localized membrane proteins whose loss causes developmental diseases in humans, assemble with Sec61 into a translocon that facilitates the biogenesis of hundreds of different multi-pass membrane proteins.

    Transport of DNA within cohesin involves clamping on top of engaged heads by Scc2 and entrapment within the ring by Scc3

    James E Collier, Byung-Gil Lee ... Kim A Nasmyth
    Rigorous biochemical and structural analyses reveal the precise topology of cohesin's association with DNA and suggest a mechanism for how DNA is transported inside the ring.
