UASt regulatory sequences drive expression of tal sequences in which 3 type-A ORFs have been deleted, along with the 1 type-B ORF, leaving only 1 type-A ORF. A single G is introduced after the start codon, causing a frameshift, which results in the translation of a spurious non-functional 13-codon ORF.
