        sydz4/syd2H larvae show defects in axonal transport, resulting in accumulations of protein in nerves.

        Maximum bouton diameter at the neuromuscular junction is slightly decreased compared to controls in sydz4/syd2H larvae.

        (Klinedinst et al., 2013)

        Axonal membrane bound cargoes and motors accumulate within the segmental nerves.
