Hereditary spastic paraplegia (HSP) is manifested as motor dysfunction stemming from axonal degeneration. Of the known 19 spastic paraplegia genes (SPGs), SPG3a encodes a multimeric integral membrane protein Atlastin. Here, the authors use zebrafish system to demonstrate the interplay between Atlastin and bone morphogenic protein signaling in motor axon development and stability.
