Polarity cascade initiated by aPKC in the periderm is transduced by adherens junction component E-cadherin to the basal epidermis during the development of zebrafish bilayered epidermis.
Selective import via bacterial ABC importers is facilitated by a hitherto unrecognized complexity in the conformational dynamics of the substrate-binding proteins.
Single-turnover studies reveal quantitative insights into the inner mechanics and unfold hidden facets in the conformational coupling of ATP binding, hydrolysis, and substrate translocation by ABC transporters.
APP interacts with KCC2 to limit the latter from tyrosine-phosphorylation and ubiquitination and thus subsequent degradation, revealing a novel molecular pathway in which APP regulates GABAergic signaling and thus inhibition in the hippocampus.
Structure of MlaFB reveals how a small binding protein and the C-terminal tail on an ATPase subunit work together to regulate the assembly and function of an ABC transporter.
A heterodimeric exporter exhibits conformational equilibria in the presence of nucleotides, suggesting a unified mechanistic model for the conformational cycle of ABC exporters.
APP mutations that either cause or prevent dementia alter APP metabolism in a complex and opposite fashion, suggesting a link between multiple APP processing events, dementia and ageing-dependent cognitive decline.
