    basic FUNCTION
  • involved in dendritic transport of RNA
  • mitotic microtubule-associated motor protein, modulates neuronal migration
  • a role in process outgrowth and axonal transport of mitochondria
  • is a key isoform of kinesin-1, which is a key molecular machinery in facilitating anterograde axonal mitochondrial transport
  • KIF5A directly regulates mitochondrial axonal transport in developing retinal ganglion cells (RGCs)
  • CELLULAR PROCESS

  • INTERACTION

    RNA
    small molecule
    protein
  • Beta-dystrobrevin, DTNB
  • Pur alpha-containing granules
  • SNPH mediates the activity-dependent immobilization of axonal mitochondria through binding to KIF5A
  • ZFYVE27 interact with other hereditary spastic paraplegia-related proteins including myelin proteolipid protein 1 (PLP1), atlastin-1 (ATL1), REEP1, REEP5 (similar to REEP1), KIF5A, KIF5B, KIF5C

    ANIMAL & CELL MODELS
  • KIF5A knockout (KIF5A( -/- )) mice die early after birth whose lungs are unexpanded, and cell bodies of lower motor neurons in the spinal cord swollen
  • Outgrowth of axons and dendrites is remarkably diminished in mouse KIF5A( -/- ) motor neurons and the number of axonal branches is reduced and sensory neurons, neurite outgrowth as well
  • Ectopic expression of Drosophila Khc carrying a human KIF5A-associated mutation (N256S) is sufficient to disturb axonal transport and to induce motoneuron disease in Drosophila
