Predicted to enable GABA receptor binding activity and myosin binding activity. Predicted to be involved in several processes, including endosome to lysosome transport; mitochondrion distribution; and organelle transport along microtubule. Predicted to be active in cytoplasmic vesicle; dendrite; and mitochondrion. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 68. Orthologous to human TRAK1 (trafficking kinesin protein 1).
