Is a key regulator of neurite extension through regulation of microtubule instabilily. Associated with punctate structures in the perinuclear cytoplasm, axons, and growth cones of developing neurons. SCG10 exists in both soluble and membrane-bound forms (By similarity). Expression is neuron-specific and found in cerebellum, forebrain, midbrain, tectum and spinal cord. Belongs to the stathmin family.
