  • enriched in axonal growth cones and interacts directly with microtubules
  • basic FUNCTION
  • may be involved in nervous system development and function
  • acts intracellularly as a microtubule-stabilizing protein required for axon and leading process development and neuronal migration in the cerebral cortex
  • essential role of FGF13 in establishing neural circuits in the cerebral cortex and enabling cognitive functions
  • not only binds to tubulins but also polymerizes and stabilizes MTs, and is likely required for the assembly of MTs in neurons
  • is required for the formation and structural refinement of axons
  • FGF13 expression is critical for hippocampal development
  • possible role for FGF13 in hair follicle growth and in the hair cycle
  • powerful role of FGF13 in control of neuronal excitability
  • is a microtubule-stabilizing protein that regulates neuronal polarization and migration
  • concerted actions of FGF13 and FGF14 regulate the polarized localization of voltage-gated sodium channels (VGSCs) that supports efficient action potential initiation

  • beyond the thermosensors, the FGF13c/SCN9A omplex is essential for sustaining the transmission of noxious heat signals
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • FGF13 regulates proliferation and differentiation of skeletal muscle by down-regulating SPRY1
  • FGF13 interacted with the sodium channel SCN9A in a heat-facilitated manner (FGF13 increased SCN9A sodium currents and maintained the membrane localization of SCN9A during noxious heat stimulation, enabling the sustained firing of action potentials)
