    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky et al.
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.

    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.

    The E3 ubiquitin ligase TRIM23 regulates adipocyte differentiation via stabilization of the adipogenic activator PPARγ

    Masashi Watanabe et al.
    TRIM23 plays a critical role in the switching from early to late adipogenic enhanceosomes by stabilizing the PPARγ protein.

    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.

    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.

    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.

    Endoplasmic reticulum stress-independent activation of unfolded protein response kinases by a small molecule ATP-mimic

    Aaron S Mendez et al.
    A rationally designed small molecule ATP-mimetic activates IRE1 and PERK signaling in cells by inducing conformational changes that template the assembly of higher-order enzymatically active structures.

    Inflammation produces catecholamine resistance in obesity via activation of PDE3B by the protein kinases IKKε and TBK1

    Jonathan Mowers et al.
    Reduced energy expenditure in obesity may result from reduced sensitivity to sympathetic activation due to inflammation-generated signals in adipose tissue.
