    miR-142 orchestrates a network of actin cytoskeleton regulators during megakaryopoiesis

    Elik Chapnik et al.
    miR-142 is instrumental for actin homeostasis, and its loss disrupts the cytoskeleton organization and thrombopoiesis of megakaryocytes.

    Orchestration of microtubules and the actin cytoskeleton in trichome cell shape determination by a plant-unique kinesin

    Juan Tian et al.
    Kinesin-like calmodulin-binding protein integrates microtubules and F-actin to assemble the cytoskeletal configuration needed for trichome formation.

    Yeast Eps15-like endocytic protein Pan1p regulates the interaction between endocytic vesicles, endosomes and the actin cytoskeleton

    Junko Y Toshima et al.
    Phosphorylation of the Eps15-like protein Pan1p regulates how endocytic compartments interact with each other and with the actin cytoskeleton.

    A viral fusogen hijacks the actin cytoskeleton to drive cell-cell fusion

    Ka Man Carmen Chan et al.
    A viral fusogen drives cell-cell fusion by hijacking the actin machinery to directly couple actin assembly with a short fusogenic ectodomain.

    Pak2 is required for actin cytoskeleton remodeling, TCR signaling, and normal thymocyte development and maturation

    Hyewon Phee et al.
    The p21-activated kinase 2 (Pak2) is an essential regulator that governs the actin cytoskeleton-dependent signaling to ensure normal thymocyte development, maturation and egress.

    Molecular mechanism for direct actin force-sensing by α-catenin

    Lin Mei et al.
    Biophysical and structural studies reveal how low piconewton forces across actin enhance binding by the critical cell-cell adhesion protein α-catenin versus its force insensitive homolog vinculin.

    Mouse T cell priming is enhanced by maturation-dependent stiffening of the dendritic cell cortex

    Daniel Blumenthal et al.
    The dendritic cell actin cytoskeleton provides a platform for T cell mechanosensing, delivering novel biophysical cues that serve as costimulatory signals for T cell activation.

    Lamellipodin promotes actin assembly by clustering Ena/VASP proteins and tethering them to actin filaments

    Scott D Hansen, R Dyche Mullins
    Lamellipodin, an important regulator of cytoskeletal and assembly cell migration, enhances the activity of Ena/VASP family actin polymerases by clustering them on leading-edge membranes and tethering them to actin filaments.
