Complete morphological regeneration depends on DLK-1 but neuronal sprouting and outgrowth is DLK-1 independent. We show that touch receptor neuron(TRN) regeneration is fully functional since animals regain their ability to respond to mechanical stimulation.

Mitochondrial localization to the axon after injury is regulated in part by dual-leucine zipper kinase 1 (DLK-1), a conserved regulator of axon regeneration.

Independent of myosin light chain activation, RHGF-1 acts via Rho-dependent kinase LET-502/ROCK and activates a conserved, retrograde DLK-1 MAPK pathway, triggering synaptic branch retraction and overgrowth of the PLM neurite in a dose-dependent manner.
Title: RHGF-1/PDZ-RhoGEF and retrograde DLK-1 signaling drive neuronal remodeling on microtubule disassembly.
Genetic, transgenic, and biochemical studies indicated that PPM-2 functions coordinately with the ubiquitin ligase activity of RPM-1 and the F-box protein FSN-1 to negatively regulate DLK-1
Title: RPM-1 uses both ubiquitin ligase and phosphatase-based mechanisms to regulate DLK-1 during neuronal development.
DLK-1 is activated by calcium-mediated dissociation from an inhibitory isoform.
