UASp regulatory sequences drive expression of Chc tagged with EGFP.
Scer\GAL4Act.PU/ChcUASp.EGFP rescues Chc4/Chc1
Scer\GAL4Act.PU/ChcUASp.EGFP fails to rescue Chc1
Expression of ChcScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4Act.PU rescues the reduced viability and sterility of Chc1/Chc4 females, but does not rescue the lethality of Chc1 mutants.
