    Antagonistic control of DDK binding to licensed replication origins by Mcm2 and Rad53

    Syafiq Abd Wahab, Dirk Remus
    The mechanism of Dbf4-dependent kinase (DDK) recruitment to replication origins and its regulation by the checkpoint have been identified.

    Restraint of presynaptic protein levels by Wnd/DLK signaling mediates synaptic defects associated with the kinesin-3 motor Unc-104

    Jiaxing Li et al.
    Synaptic defects previously attributed to loss of kinesin function are found to be mediated by the Wnd/DLK axonal injury signaling pathway, which restrains the total levels of presynaptic proteins in response to their accumulation.

    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.

    Dynamic relocalization of replication origins by Fkh1 requires execution of DDK function and Cdc45 loading at origins

    Haiyang Zhang et al.
    Establishment of replication-timing involves Fkh1-dependent recruitment and execution of DDK function in G1 phase resulting in dynamic relocalization of origins within the nucleus in anticipation of CDK-dependent origin activation.

    Activation of MAP3K DLK and LZK in Purkinje cells causes rapid and slow degeneration depending on signaling strength

    Yunbo Li et al.
    The activity levels of two closely related MAPKKK are differentially regulated in Purkinje neuron survival.

    FBXL19 recruits CDK-Mediator to CpG islands of developmental genes priming them for activation during lineage commitment

    Emilia Dimitrova et al.
    The ZF-CxxC protein FBXL19 recruits kinase-associated Mediator to CpG islands of silent developmental genes in embryonic stem cells, which primes these genes for activation during differentiation and is required for embryonic development.

    Inhibiting poly(ADP-ribosylation) improves axon regeneration

    Alexandra B Byrne et al.
    In C. elegans and mouse neurons, the balance between poly(ADP-ribose) glycohydrolases and poly(ADP-ribose) polymerases regulates axon regeneration downstream of DLK-1/MAPKKK signaling.

    Visualizing the metazoan proliferation-quiescence decision in vivo

    Rebecca C Adikes et al.
    During organismal development, CDK activity at mitotic exit is predictive of future cell behavior, indicating whether a cell will divide again or enter a quiescent state.

    Proteasome dysfunction triggers activation of SKN-1A/Nrf1 by the aspartic protease DDI-1

    Nicolas J Lehrbach, Gary Ruvkun
    Post-translational processing of the SKN-1A/Nrf1 transcription factor regulates proteasome expression.

    Dual leucine zipper kinase-dependent PERK activation contributes to neuronal degeneration following insult

    Martin Larhammar et al.
    Two seemingly distinct cellular stress response pathways that contribute to neurodegeneration after axonal insults are now revealed to be under the control of a single master regulator of the neuronal injury response, the kinase DLK.
