We show that loss-of-function mutations in kinases of the MLK-1 pathway (mlk-1, mek-1, and kgb-1/jnk) function cell-autonomously in neurons to suppress defects in synapse formation and axon termination caused by rpm-1 loss of function. Our genetic analysis also suggests that the phosphatase PPM-1, like RPM-1, is a potential inhibitor of kinases in the MLK-1 pathway.
