UAS regulatory sequences drive expression of Fic carrying the amino acid replacement I271D (this mutation disrupts dimerization). The protein is tagged at the C-terminal end with Tag:V5 and Tag:polyHis.
The co-expression of FicI271D.Scer\UAS.T:SV5\V5.T:Zzzz\His6 rescues the small and rough eye phenotype observed in Fic30C homozygotes expressing FicE247G.Scer\UAS.T:SV5\V5.T:Zzzz\His6 under the control of Scer\GAL4GMR.long.
