Proteins such as UNC-76 that associate with kinesin motors are important in directing neurite extension. A small Caenorhabditis elegans coiled-coil protein, UNC-69, has now been shown to interact with UNC-76 and to be involved in axonal (but not dendritic) transport and outgrowth, as well as synapse formation.
