UASt regulatory sequences drive expression of an inverted repeat of TART-element\gag corresponding to nt 1094-1638 in the nucleotide sequence of GenBank accession number U14101.
A non-specific late larval/pupal lethal phenotype is observed when Scer\GAL4Act5C.PI or Scer\GAL4T80 drives expression of TART-element\gagdsRNA.Scer\UAS.T1IR.
