    Cooperation between tropomyosin and α-actinin inhibits fimbrin association with actin filament networks in fission yeast

    Jenna R Christensen et al.
    The contractile ring actin binding proteins tropomyosin Cdc8 and a-actinin Ain1 synergize to effectively compete with the endocytic actin patch protein fimbrin Fim1 for associating with F-actin networks.

    DDR2 controls breast tumor stiffness and metastasis by regulating integrin mediated mechanotransduction in CAFs

    Samantha VH Bayer et al.
    The action of the collagen receptor DDR2 in CAFs regulates Rap1-Talin1 mediated Integrin mechanotransduction in breast tumors to impact tumor stiffness and metastases.

    Multi-phosphorylation reaction and clustering tune Pom1 gradient mid-cell levels according to cell size

    Veneta Gerganova et al.
    Advanced microscopy techniques reveal that clusters of Pom1 kinase at the membrane represent the functional unit that shape the concentration gradients and modulate Pom1 mid-cell levels according to cell size.

    Reconstruction of Par-dependent polarity in apolar cells reveals a dynamic process of cortical polarization

    Kalyn Kono et al.
    Par-complex-dependent cell polarity can be cell-autonomously conferred to non-polar Drosophila S2 cells, unveiling temporal patterns toward the cortical localization of Par-complex aggregates that include a meshwork containing unit segments.

    Genetic diversity of CHC22 clathrin impacts its function in glucose metabolism

    Matteo Fumagalli et al.
    Natural selection shaped CHC22 clathrin genetic variation in humans with different diets and potentially influenced the human insulin response.

    Sterol transfer by atypical cholesterol-binding NPC2 proteins in coral-algal symbiosis

    Elizabeth Ann Hambleton et al.
    Diversification of a conserved cholesterol binder drives functional replacement of cholesterol with symbiont-produced sterols in corals living in nutrient-poor environments.

    The COMA complex interacts with Cse4 and positions Sli15/Ipl1 at the budding yeast inner kinetochore

    Josef Fischböck-Halwachs et al.
    The chromosomal passenger complex interacts with the inner kinetochore COMA complex through the Ctf19 C-terminus in vitro which is shown to be important for mediating accurate chromosome segregation.
