Animals expressing AtpαScer\UAS.cSa under the control of Scer\GAL4nrv1.PS die by the late first larval instar. Animals expressing AtpαScer\UAS.cSa under the control of Scer\GAL4nrv2.PS are less sensitive to ouabain than wild-type animals at the highest concentration of ouabain tested (5mM). Adults expressing AtpαScer\UAS.cSa under the control of Scer\GAL4nrv2.PS show temporary paralysis or uncontrolled wing beating after brief mechanical stimulation.
