    A second DNA binding site on RFC facilitates clamp loading at gapped or nicked DNA

    Xingchen Liu, Christl Gaubitz ... Brian A Kelch
    Structural, biochemical, and cellular data reveal the mechanism by which the clamp loader attaches sliding clamps at gapped and nicked DNA to support DNA damage repair.

    Cryo-EM structures reveal high-resolution mechanism of a DNA polymerase sliding clamp loader

    Christl Gaubitz, Xingchen Liu ... Brian A Kelch
    Cryo-EM structures of the eukaryotic clamp loader illustrate the large conformational changes that the clamp loader ATPase undergoes to open the circular sliding clamp and place it onto primer–template DNA.

    Genomic epidemiology of artemisinin resistant malaria

    MalariaGEN Plasmodium falciparum Community Project
    Plasmodium falciparum kelch13 mutations that cause artemisinin resistant malaria in Southeast Asia show markedly different patterns of evolutionary selection in Africa.

    Local emergence in Amazonia of Plasmodium falciparum k13 C580Y mutants associated with in vitro artemisinin resistance

    Luana C Mathieu, Horace Cox ... Lise Musset
    The de novo selection of a mutation responsible for Plasmodium falciparum in vitro artemisinin resistance is confirmed in Guyana, making artemisinin combination therapies vulnerable to complete resistance in this region.

    KLHL41 stabilizes skeletal muscle sarcomeres by nonproteolytic ubiquitination

    Andres Ramirez-Martinez, Bercin Kutluk Cenik ... Eric N Olson
    KLHL41 acts as a poly-ubiquitin dependent chaperone that prevents the formation of pathogenic nebulin aggregates associated with muscle disease.

    Multistep loading of a DNA sliding clamp onto DNA by replication factor C

    Marina Schrecker, Juan C Castaneda ... Richard K Hite
    Single-particle cryo-EM structures reveal a multistep process of how DNA is loaded into the DNA sliding clamp proliferating cell nuclear antigen by the canonical clamp loader replication factor C.

    Genetic surveillance in the Greater Mekong subregion and South Asia to support malaria control and elimination

    Christopher G Jacob, Nguyen Thuy-Nhien ... Olivo Miotto
    Large-scale genetic surveillance of malaria implemented by National Malaria Control Programmes informs public health decision makers about the spread of strains resistant to antimalarials.

    Dynamic regulation of inter-organelle communication by ubiquitylation controls skeletal muscle development and disease onset

    Arian Mansur, Remi Joseph ... Vandana A Gupta
    Novel disease pathways underlie disease pathogenesis in Kelch-related nemaline myopathy through proteomic remodeling.

    Expanded genetic screening in Caenorhabditis elegans identifies new regulators and an inhibitory role for NAD+ in axon regeneration

    Kyung Won Kim, Ngang Heok Tang ... Yishi Jin
    A function-based genetic screen using the Caenorhabditis elegans axotomy model identifies new regulators and an inhibitory role for NAD+ in axon regeneration, expanding the understanding of axon injury responses and regeneration.
