A TI{2A-GAL4(DBD)::Zip-} cassette has been inserted in-frame into the endogenous Myo31DF locus. The presence of the 2A peptide results in the GAL4(DBD)::Zip- hemidriver being expressed as a separate protein under the control of endogenous Myo31DF regulatory sequences. The TI{2A-GAL4(DBD)::Zip-} cassette was inserted via the CRISPR/Cas-9 drop-in technique. The sgRNA sequence used to target the gene was: CCATGGACACTTGGTCGAGG.
