UASt regulatory sequences drive expression of metro-B.
Scer\GAL4αTub84B.PL/metroB.UAS rescues metro47
Expression of metroB.Scer\UAS under the control of Scer\GAL4αTub84B.PL rescues the reduction in bouton number and increase in bouton size which is seen at the neuromuscular junction in metro47 mutants.
