Required for kinesin-mediated axonal transport of mitochondria to nerve terminals (PubMed:12495622, PubMed:16887820, PubMed:16717129). The oocyte acquires the majority of its mitochondria by competitive bidirectional transport along microtubules mediated by the Milton adapter. Mitochondria enter the young oocyte en mass from interconnected germ cells to generate the large aggregate known as the Balbiani body (PubMed:16887820). Milt and Miro form an essential protein complex that links Khc to mitochondria for light chain-independent, anterograde transport of mitochondria (PubMed:16717129). Interacts with Miro (PubMed:16717129). Interacts with OGT (PubMed:24995978). Note=Mitochondrial transport by milt and Khc is independent of Klc. Expressed primarily in axons and synapses. Expressed both maternally and zygotically. Flies show aberrant synaptic transmission in photoreceptors despite normal phototransduction. Synaptic terminals and axons lack mitochondria, although mitochondria are numerous in neuronal cell bodies. Synaptic vesicles continue to be transported to and concentrated at synapses. In mutant oocytes mitochondria are transported prematurely and excessively. Was named 'Milton' after the blind British poet. Belongs to the milton family.
