Directed cell migration is critical for metazoan development. During Caenorhabditis elegans development many neuronal, muscle and other cell types migrate. Multiple classes of proteins have been implicated in cell migration including secreted guidance cues, receptors for guidance cues and intracellular proteins that respond to cues to polarize cells and produce the forces that move them. In addition, cell surface and secreted proteases have been identified that may clear the migratory route and process guidance cues. We report here that mnp-1 is required for neuronal cell and growth cone migrations. MNP-1 is expressed by migrating cells and functions cell autonomously for cell migrations. We also find a genetic interaction between mnp-1 and cam-1, which encodes a Ror receptor tyrosine kinase required for some of the same cell migrations.
