UASt regulatory sequences drive expression of α-Cat that lacks amino acid residues 152-272. The protein is tagged with Tag:V5. Synonymous mutations have been introduced into the portion of the α-Cat coding region that corresponds to the target sequence of the P{TRiP.HMS00317} RNAi line, rendering this transgene insensitive to RNAi mediated by P{TRiP.HMS00317}.
