    ATM regulation of IL-8 links oxidative stress to cancer cell migration and invasion

    Wei-Ta Chen et al.
    The ATM kinase has an unanticipated role in tumor progression through the regulation of cell migration by oxidative stress.

    Re-expression of SMARCA4/BRG1 in small cell carcinoma of ovary, hypercalcemic type (SCCOHT) promotes an epithelial-like gene signature through an AP-1-dependent mechanism

    Krystal Ann Orlando et al.

    ATP hydrolysis by the viral RNA sensor RIG-I prevents unintentional recognition of self-RNA

    Charlotte Lässig et al.
    Mutations within the ATPase domain of RIG-I in patients with Singleton-Merten Syndrome prevent ATP-hydrolysis dependent dissociation of RIG-I from double-stranded RNA and lead to unintentional constitutive signaling through increased binding of endogenous RNA.

    Molecular structure of human KATP in complex with ATP and ADP

    Kenneth Pak Kin Lee et al.
    MgADP binding to the high-affinity 'consensus' ATPase active site of SUR1 and remodeling of the L0-loop (lasso region) overrides tonic ATP inhibition of KATP channels.

    Large-scale filament formation inhibits the activity of CTP synthetase

    Rachael M Barry et al.
    The accumulation of its product, cytidine triphosphate, encourages the enzyme CTP synthetase (CtpS) to form large-scale polymers and inhibits the enzyme's activity.

    Cryo-EM structures of the autoinhibited E. coli ATP synthase in three rotational states

    Meghna Sobti et al.
    A molecular model that provides a framework for interpreting the wealth of functional information obtained on the E. coli F-ATP synthase has been generated using cryo-electron microscopy.

    Inactivation of the ATMIN/ATM pathway protects against glioblastoma formation

    Sophia M Blake et al.
    Deletion of the ATM cofactor ATMIN reduces PDGFRA expression and strongly suppresses tumorigenesis in a TP53-deficient mouse model of glioblastoma.

    Structure and conformational states of the bovine mitochondrial ATP synthase by cryo-EM

    Anna Zhou et al.
    Structural analysis of the ATP synthase – in combination with evolutionary covariance analysis – reveals the fold of the a subunit and shows that the enzyme can adopt several different conformations, which support the Brownian ratchet model for generating rotation.

    Identification of cryptic subunits from an apicomplexan ATP synthase

    Diego Huet et al.
    A phylum-specific ATP synthase subunit is needed for proper mitochondrial function and stability of the complex in Toxoplasma gondii.
