Microtubule-dependent motor required for slow axonal transport of neurofilament proteins (NFH, NFM and NFL). Can induce formation of neurite-like membrane protrusions in non-neuronal cells in a ZFYVE27-dependent manner. The ZFYVE27-KIF5A complex contributes to the vesicular transport of VAPA, VAPB, SURF4, RAB11A, RAB11B and RTN3 proteins in neurons. Required for anterograde axonal transportation of MAPK8IP3/JIP3 which is essential for MAPK8IP3/JIP3 function in axon elongation.

This study identified three pathogenic KIF5A mutations in Korean Charcot-Marie-Tooth neuropathy type 2 patients by whole exome sequencing. Two mutations (p.Arg204Trp and p.Arg280His) were previously reported, but p.Leu558Pro was determined to be a novel de novo mutation. PMID: 29892902
