    Cell autonomous regulation of hippocampal circuitry via Aph1b-γ-secretase/neuregulin 1 signalling

    Pietro Fazzari et al.
    Genetic rescue experiments reveal that γ-secretase enzymes containing Aph1b subunits control signalling by type III neuregulin 1, with implications for schizophrenia.

    Sampling the conformational space of the catalytic subunit of human γ-secretase

    Xiao-chen Bai et al.
    A masked cryo-EM image classification approach and the structure of an inhibitor-bound complex provide insights into the molecular flexibility of the catalytic subunit of gamma-secretase.

    The metal transporter ZIP13 supplies iron into the secretory pathway in Drosophila melanogaster

    Guiran Xiao et al.
    Drosophila ZIP13 (Slc39a13), a presumed zinc importer, is responsible for iron delivery to the secretory pathway.

    Golgi-independent secretory trafficking through recycling endosomes in neuronal dendrites and spines

    Aaron B Bowen et al.
    Neurons use a non-canonical secretory network to deliver select proteins to postsynaptic sites in dendrites.

    A secretory kinase complex regulates extracellular protein phosphorylation

    Jixin Cui et al.
    A pseudokinase in the secretory pathway, Fam20A, activates the real Golgi casein kinase, Fam20C, via a unique mechanism that is lost in human diseases.

    The amyloid-beta forming tripeptide cleavage mechanism of γ-secretase

    David M Bolduc et al.
    The protease γ-secretase generates amyloid-beta peptides using a mechanism that is driven by the stabilization of an enzyme-substrate scisson complex.

    The structure and dynamics of secretory component and its interactions with polymeric immunoglobulins

    Beth M Stadtmueller et al.
    The ectodomain of the human polymeric Ig receptor maintains a closed triangular shape that binds and excludes bacteria in mucosa, or opens to bind and transport polymeric Ig ligands across epithelial cells.

    Ovulation in Drosophila is controlled by secretory cells of the female reproductive tract

    Jianjun Sun, Allan C Spradling
    Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.
