    Activation of GCN2 kinase by ribosome stalling links translation elongation with translation initiation

    Ryuta Ishimura et al.
    Activation of the integrated stress response by stalled translation elongation complexes attenuates neurodegeneration, and demonstrates a protective link between a decrease in the rate of translation initiation and defects in translation elongation.

    Changes in the free-energy landscape of p38α MAP kinase through its canonical activation and binding events as studied by enhanced molecular dynamics simulations

    Antonija Kuzmanic et al.
    Extensive molecular dynamics simulations enhanced by advanced sampling techniques give a detailed view of p38α canonical activation mechanism, which reveals novel key electrostatic interactions that are put in context of existing experimental data.

    Autoinhibition of Bruton's tyrosine kinase (Btk) and activation by soluble inositol hexakisphosphate

    Qi Wang et al.
    A key B-cell tyrosine kinase that adopts an autoinhibited conformation, and can be activated by either membrane recruitment or soluble inositol hexakisphosphates in solution.

    A dynamic mechanism for allosteric activation of Aurora kinase A by activation loop phosphorylation

    Emily F Ruff et al.
    Phosphorylation of Aurora A does not trigger a population shift to the active state as previously thought, but instead switches the kinase on by tuning the structure and dynamics of a dynamically sampled subpopulation.

    An evolutionarily conserved mechanism for cAMP elicited axonal regeneration involves direct activation of the dual leucine zipper kinase DLK

    Yan Hao et al.
    Axonal damage sensing kinase DLK is a direct target and mediator of the cAMP effector kinase PKA in a unified mechanism for stimulating axonal regeneration.

    The HIV-1 Tat protein recruits a ubiquitin ligase to reorganize the 7SK snRNP for transcriptional activation

    Tyler B Faust et al.
    The HIV-1 Tat protein hijacks host non-degradative ubiquitination to trigger the nuclear import of the transcription elongation factor, P-TEFb.

    SAV1 promotes Hippo kinase activation through antagonizing the PP2A phosphatase STRIPAK

    Sung Jun Bae et al.
    The scaffold protein SAV1 counteracts PP2A to activate Hippo kinases.

    FAM150A and FAM150B are activating ligands for anaplastic lymphoma kinase

    Jikui Guan et al.
    The secreted molecules FAM150A and FAM150B bind to the ALK RTK extracellular domain, potently activating the receptor activation and driving downstream signaling events.
