Enables several functions, including GABA receptor binding activity; TPR domain binding activity; and kinesin binding activity. Involved in several processes, including dendritic transport of mitochondrion; endosome to lysosome transport; and generation of neurons. Located in several cellular components, including axonal growth cone; dendrite; and neuronal cell body. Colocalizes with early endosome. Orthologous to human TRAK2 (trafficking kinesin protein 2).
