UAS regulatory sequences drive expression of a catalytically inactive form of Fic (carries the amino acid replacement H375A). The protein is tagged at the C-terminal end with Tag:V5 and Tag:polyHis.
The expression of FicH375A.Scer\UAS.T:SV5\V5.T:Zzzz\His6 under the control of either Scer\GAL4da.G32, alone or in an Fic30C homozygosity background, is viable.
The co-expression of FicH375A.Scer\UAS.T:SV5\V5.T:Zzzz\His6 fails to rescue the small and rough eye phenotype of Fic30C homozygotes expressing FicE247G.Scer\UAS.T:SV5\V5.T:Zzzz\His6 under the control of Scer\GAL4GMR.long.
