    FAK/PYK2 promotes the Wnt/β-catenin pathway and intestinal tumorigenesis by phosphorylating GSK3β

    Chenxi Gao, Guangming Chen ... Jing Hu
    Dual FAK/PYK2 kinase inhibition disrupts GSK3β phosphorylation and may present a new treatment for colorectal cancer in patients carrying APC mutations.

    SIRT2 deacetylase regulates the activity of GSK3 isoforms independent of inhibitory phosphorylation

    Mohsen Sarikhani, Sneha Mishra ... Nagalingam R Sundaresan
    Mass spectroscopy, molecular modeling and/or molecular dynamics simulations reveal how acetylation regulates the activity of GSK3 isoforms independent of inhibitory phosphorylation.

    A genetic screen in macrophages identifies new regulators of IFNγ-inducible MHCII that contribute to T cell activation

    Michael C Kiritsy, Laurisa M Ankley ... Andrew J Olive
    Med16 and GSK3b regulate interferon gamma-mediated MHCII expression in macrophages and are required for CD4+ T cell activation.

    mTORC1 is necessary but mTORC2 and GSK3β are inhibitory for AKT3-induced axon regeneration in the central nervous system

    Linqing Miao, Liu Yang ... Yang Hu
    The kinase AKT acts as a nodal point that coordinates both positive and negative cues to regulate the regeneration of central nervous system axons in adult mice.

    Characterization of a Toxoplasma effector uncovers an alternative GSK3/β-catenin-regulatory pathway of inflammation

    Huan He, Marie-Pierre Brenier-Pinchart ... Alexandre Bougdour
    A genetic screen in combination with biochemical approaches reveal hijacking of the host β-catenin destruction complex by the parasite T. gondii to reprogram immune gene expression.

    Sequential phosphorylation of NDEL1 by the DYRK2-GSK3β complex is critical for neuronal morphogenesis

    Youngsik Woo, Soo Jeong Kim ... Sang Ki Park
    Sequential phosphorylation of NDEL1 Ser336/Ser332 by DYRK2 and GSK3β is a novel regulatory step for actin dynamics that contributes to the neurite outgrowth and neuronal arborization in the developing brain.

    PTEN negatively regulates the cell lineage progression from NG2+ glial progenitor to oligodendrocyte via mTOR-independent signaling

    Estibaliz González-Fernández, Hey-Kyeong Jeong ... Shin H Kang
    OPC-specific genetic inhibition of Akt upstream and downstream molecules in the mouse, and simultaneous OPC fate analysis reveal that PTEN-AKT-GSK3b forms a persistent negative signaling pathway for OL development, in parallel with the AKT-mTORC1 pathway.

    The Axin scaffold protects the kinase GSK3β from cross-pathway inhibition

    Maire Gavagan, Noel Jameson, Jesse G Zalatan
    A biochemical approach using the Wnt pathway as a model system demonstrates a new mechanism for specificity in interconnected signaling networks through scaffold-mediated shielding of bound proteins.
    1. Neuroscience

    Discovery and characterization of a specific inhibitor of serine-threonine kinase cyclin-dependent kinase-like 5 (CDKL5) demonstrates role in hippocampal CA1 physiology

    Anna Castano, Margaux Silvestre ... Alison D Axtman
    Specific inhibition of cyclin-dependent kinase-like 5 (CDKL5), a kinase linked to a severe neurodevelopmental disorder, demonstrates an important role in the regulation of excitatory hippocampal synapses and synaptic plasticity that was not previously appreciated in rodent knock-out models.
