Motor for anterograde axonal transport of synaptic vesicle precursors (Probable). Also required for neuronal dense core vesicles (DCVs) transport to the dendritic spines and axons (PubMed:29166604, PubMed:30021165). The interaction calcium-dependent with CALM1 increases vesicle motility and interaction with the scaffolding proteins PPFIA2 and TANC2 recruits DCVs to synaptic sites (PubMed:30021165). {Experimental EvidencePubMed:29166604, Experimental EvidencePubMed:30021165, Curator Inference}.
