During embryonic development, the two Caenorhabditis elegans HSN motor neurons migrate from their birthplace in the tail to positions near the middle of the embryo. Here, we demonstrate that of all cells that undergo long-range migrations, only the HSNs are affected in animals that lack function of the egl-43 gene. We also show that egl-43 function is required for normal development of phasmid neurons, which are sensory neurons located in the tail. The egl-43 gene encodes two proteins containing zinc finger motifs that are similar to the zinc fingers of the murine Evi-1 proto-oncoprotein. Our genetic and molecular results suggest that egl-43 encodes two transcription factors and acts to control HSN migration and phasmid neuron development, presumably by regulating other genes that function directly in these processes.
