UAS regulatory sequences drive expression of esc.
Scer\GAL4elav-C155/escUAS.cUa rescues esc21
The dendrite defects seen in single cell class IV dendrite arborisation (da) neuron clones that are homozygous for esc21 are rescued by expression of escScer\UAS.cUa under the control of Scer\GAL4elav-C155.
