      Reference

      Expression of LamCN496I.Scer\UAS under the control of Scer\GAL4C57 leads to larval locomotion defects and semi-lethality at the pupal stage. A subset of the larval body wall muscles show abnormally shaped and spaced nuclei, and disorganization of the actin cytoskeleton.

      (Dialynas et al., 2015)

      Third instar larvae expressing LamCN496I.Scer\UAS under the control of Scer\GAL4C57 show reduced mobility.
