  • FYVE-finger family
  • CATEGORY regulatory
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,organelle,endoplasmic reticulum
  • localizes to the endosomal membrane traffic compartment, suggesting that the long axons of the corticospinal tract may be especially vulnerable to endosomal dysfunction
  • localizes on a late endosomal/lysosomal compartments
  • broadly expressed in neurons, associates with intracellular vesicles immunopositive for the early endosomal marker EEA1, and co-fractionates with a component of the AP5 complex
  • basic FUNCTION
  • may be playing a role in intracellular trafficking
  • involved in the abscission step during cytokinesis
  • important for proper development of the axons of spinal motor neurons
  • role in autophagy and required for autophagosome maturation
  • involved in the endolysosomal system
  • CELLULAR PROCESS cell cycle, division, mitosis
    PHYSIOLOGICAL PROCESS nervous system , cellular trafficking transport

  • microtubule motor KIF13A and tetratricopeptide repeat domain 19, TTC19
  • KIAA0415
  • AP-5 subunits

    Candidate gene
    Therapy target
  • SPG15 knock-down in zebrafish by morpholino antisense oligonucleotides lead to locomotor impairment and abnormal branching of spinal cord motor neurons at the neuromuscular junction
  • SPG15 knockdown causes the cation-independent mannose 6-phosphate receptor to become trapped in clusters of early endosomes as well as the tubulation of EEA1-positive endosomesof HeLa cellof HeLa cells
  • autophagy defects with autophagosome accumulation is observed also in neuronal cells upon spastizin silencing
  • Zfyve26 knockout mice develop late-onset spastic paraplegia with cerebellar ataxia, display axon degeneration and progressive loss of both cortical motoneurons and Purkinje cells in the cerebellum
  • an increase of Lamp1-positive membrane compartments with higher densities in Zfyve26 knockout mice
