    Ezrin defines TSC complex activation at endosomal compartments through EGFR–AKT signaling

    Giuliana Giamundo, Daniela Intartaglia ... Ivan Conte
    Ezrin controls endo-lysosomal signaling by maintaining TSC inhibition through EGFR signaling, activating mTORC1, and inhibiting lysosomal function, unveiling a critical endosome–lysosome network essential for autophagy and cellular homeostasis.

    PDGFRα signaling regulates Srsf3 transcript binding to affect PI3K signaling and endosomal trafficking

    Thomas E Forman, Marcin P Sajek ... Katherine A Fantauzzo
    Upon PDGFRα signaling in mouse embryonic palatal mesenchyme cells, Srsf3 exhibits differential transcript binding, resulting in retention of the receptor in early endosomes and increased downstream PI3K-mediated Akt signaling.

    RETRACTED: Arginine methylation of SHANK2 by PRMT7 promotes human breast cancer metastasis through activating endosomal FAK signalling

    Yingqi Liu, Lingling Li ... Yu Zhang
    PRMT7-mediated SHANK2 methylation regulates breast cancer metastasis by activating endosomal FAK signals, and may provide potential clues for tumour metastasis treatment strategies.

    Endosomal chemokine receptor signalosomes regulate central mechanisms underlying cell migration

    Hyunggu Hahn, Carole Daly ... Alex RB Thomsen
    Cell biological approaches and spatiotemporally resolved proteome profiling demonstrate that the chemokine receptor CCR7 can activate G proteins after being internalized into endosomes, from where it regulates Rac1-dependent chemotaxis.

    Kinetics of cytokine receptor trafficking determine signaling and functional selectivity

    Jonathan Martinez-Fabregas, Stephan Wilmes ... Ignacio Moraga
    Engineering cytokines to exhibit different receptor binding dwell times is a useful strategy to decouple their functional pleiotropy and reduce their toxicity in the clinic.

    Compartment-specific opioid receptor signaling is selectively modulated by different dynorphin peptides

    Jennifer M Kunselman, Achla Gupta ... Manojkumar A Puthenveedu
    Different dynorphins, which signal similarly from the cell surface, can differentially localize G protein-coupled receptors to specific subcellular compartments and cause divergent receptor fates and distinct spatiotemporal patterns of signaling.

    β-Arrestin-dependent and -independent endosomal G protein activation by the vasopressin type 2 receptor

    Carole Daly, Akim Abdul Guseinov ... Bianca Plouffe
    The vasopressin type 2 receptor promotes dual Gαs and Gαq/11 signaling at early endosomes in β-arrestin-dependent and -independent manners.

    BRAF activates PAX3 to control muscle precursor cell migration during forelimb muscle development

    Jaeyoung Shin, Shuichi Watanabe ... Thomas Braun
    Genetic and biochemical approaches identify a new component of the cellular signaling machinery driving migration of limb muscle precursor cells during mouse embryogenesis and reveal the underlying molecular mechanism.

    A postsynaptic PI3K-cII dependent signaling controller for presynaptic homeostatic plasticity

    Anna G Hauswirth, Kevin J Ford ... Graeme W Davis
    A screen encompassing all kinases and phosphatases reveals that PI3K-cII, PI3K-cIII and Rab11-dependent recycling endosomes comprise a novel, postsynaptic 'signaling controller' that is part of an integrated, trans-synaptic signaling system necessary for presynaptic homeostatic plasticity.
