Enables TPR domain binding activity. Involved in axonal transport of mitochondrion; dendrite morphogenesis; and positive regulation of axonogenesis. Located in axonal growth cone; dendrite; and perinuclear region of cytoplasm. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 68. Orthologous to human TRAK1 (trafficking kinesin protein 1). [provided by Alliance of Genome Resources, Apr 2022]
