UAS regulatory sequences drive expression of a full-length COX4 open reading frame (ORF) that is tagged at the C-terminal end with three copies of the Tag:HA epitope. The ORF is flanked by a pair of incompatible FRT sites (FRT5 and FRT2), which allows for future in vivo exchange of either the promoter or tag sequence.
