    Electron cryo-microscopy of bacteriophage PR772 reveals the elusive vertex complex and the capsid architecture

    Hemanth KN Reddy et al.
    The structure and composition of the elusive vertex complex in Tectiviridae is finally revealed and the newly reported protein conformations help to maintain the capsid architecture.

    Cell-autonomous regulation of epithelial cell quiescence by calcium channel Trpv6

    Yi Xin et al.
    Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca2+ signaling pathway maintaining the quiescent state.

    A dynamic charge-charge interaction modulates PP2A:B56 substrate recruitment

    Xinru Wang et al.
    A novel dynamic charge-charge interaction between B56 and a subset of PP2A-B56 substrates is essential for substrate specificity, dephosphorylation and, for KIF4A, binding condensin I.

    Division of labour between PP2A-B56 isoforms at the centromere and kinetochore

    Giulia Vallardi et al.
    Distinct PP2A-B56 complexes use isoform-selective interactions to localise to either the centromere or kinetochore and control different processes during mitosis.

    The AFF4 scaffold binds human P-TEFb adjacent to HIV Tat

    Ursula Schulze-Gahmen et al.
    Structure-function analysis of the super elongation complex formed when HIV replicates inside cells reveals that the HIV-1 Tat protein binds to a cleft between P-TEFb, an enzyme that is involved in normal transcription, and AFF4, a protein that is used to build the super elongation complex

    A polymorphism in the tumor suppressor p53 affects aging and longevity in mouse models

    Yuhan Zhao et al.
    A mouse model reveals that a p53 SNP impacts longevity via modulating the balance of cancer risk and the self-renewal function of stem/progenitor cells, which supports a role of p53 in regulation of longevity.

    A novel pH-dependent membrane peptide that binds to EphA2 and inhibits cell migration

    Daiane S Alves et al.
    The transmembrane domain of the EphA2 receptor has been transformed into a novel amphitropic peptide that binds to the EphA2 receptor and inhibits cell migration.
