    Loss of Ptpn11 (Shp2) drives satellite cells into quiescence

    Joscha Griger et al.
    The stem cells of the postnatal muscle allow postnatal muscle growth and repair and withdraw from the cell cycle when the tyrosine phosphatase Ptpn11 (Shp2) is inhibited or mutated in mice.

    Time-resolved phosphoproteomics reveals scaffolding and catalysis-responsive patterns of SHP2-dependent signaling

    Vidyasiri Vemulapalli et al.
    Monitoring SHP2 phosphoproteome dynamics identifies new substrate sites and sites protected from dephosphorylation by its SH2 domains, highlighting distinct scaffolding and catalytic activities in effecting a transmembrane signaling response.

    FcγRIIb-SHIP2 axis links Aβ to tau pathology by disrupting phosphoinositide metabolism in Alzheimer's disease model

    Tae-In Kam et al.
    By binding to Fc gamma receptor IIb, amyloid beta induces a series of phosphorylation events that mediate the damaging effects of hyperphosphorylated tau proteins in Alzheimer's disease.

    Structural basis for interdomain communication in SHIP2 providing high phosphatase activity

    Johanne Le Coq et al.
    The SHIP2 inositol phosphatase is an important upstream regulator of the Akt signaling pathway, which requires a catalytic core formed by the phosphatase domain tightly packed to a C2 domain for its function.

    Specific Eph receptor-cytoplasmic effector signaling mediated by SAM–SAM domain interactions

    Yue Wang et al.
    Comparative structural studies reveal how the cytoplasmic tails of Eph receptors can differentiate different downstream target proteins via highly specific SAM–SAM domain interactions.

    The contribution of asymptomatic SARS-CoV-2 infections to transmission on the Diamond Princess cruise ship

    Jon C Emery et al.
    Nearly 75% of SARS-CoV-2 infections on the Diamond Princess were asymptomatic, half were never detected, and asymptomatic infections may have contributed substantially to transmission.

    Marked synergy by vertical inhibition of EGFR signaling in NSCLC spheroids shows SOS1 is a therapeutic target in EGFR-mutated cancer

    Patricia L Theard et al.
    Combined EGFR and SOS1 inhibition synergize to inhibit NSCLC spheroid growth.

    Heparan sulfates are critical regulators of the inhibitory megakaryocyte-platelet receptor G6b-B

    Timo Vögtle et al.
    Heparan sulfates in the vessel wall bind and regulate signaling from the megakaryocyte/platelet-specific inhibitory receptor G6b-B, a critical regulator of platelet homeostasis.

    Crk proteins transduce FGF signaling to promote lens fiber cell elongation

    Tamica N Collins et al.
    Crk proteins are critical mediators of FGF signaling to control cell shape changes.

    Fine-scale computations for adaptive processing in the human brain

    Elisa Zamboni et al.
    Laminar fMRI reveals that adaptive processing involves recurrent processing within visual cortex and top-down influences from posterior parietal cortex via feedback.
