    ..DLK-1 protein levels are elevated in rpm-1 mutants. The RPM-1 RING finger can stimulate ubiquitination of DLK-1. Our data reveal a presynaptic role of a previously unknown p38 MAP kinase cascade. ..

    ..We have also identified a C. elegans gene that encodes a protein kinase similar to mammalian MAPK/ERK Kinase (MEK) 4 whose promoter is active in the pharynx. It is phosphorylated by TAO1 in vitro and physically interacts with TAO1. ..

    ..These two MAPKs are coregulated by the E3 ubiquitin ligase RPM-1(Phr1) via targeted degradation of the MAPKKKs DLK-1 and MLK-1 and by the MAPK phosphatase VHP-1(MKP7), which negatively regulates both PMK-3(p38) and KGB-1(JNK). ..

    ..elegans is required for P. aeruginosa resistance, but not through the regulation of DLK-1. In summary, our results indicate that different upstream MAPKKKs or MAPKKs regulate the activation of PMK-1 in response to P. Aeruginosa. ..

    ..We conclude that after axon injury, activation of this MAP kinase cascade is required to switch the mature neuron from an aplastic state to a state capable of growth. ..

    ..Our findings identify the DLK-1 pathway as a regulator of mRNA stability in synapse formation and maintenance and also in adult axon regeneration. ..

    ..We propose that FSN-1 may negatively regulate insulin/IGF signalling, in part, through EGL-3-dependent insulin-like ligand processing. ..
