Spastin, the protein mutated in autosomal dominant hereditary spastic paraplegia, is involved in microtubule dynamics.

Abstract excerpt

Hereditary spastic paraplegia (HSP) is characterized by progressive weakness and spasticity of the lower limbs, caused by the specific degeneration of the corticospinal tracts, the longest axons in humans. Most cases of the autosomal dominant form of the disease are due to mutations in the SPG4 gene, which encodes spastin, an ATPase belonging to the AAA family. The cellular pathways in which spastin operates and...
