A TI{2A-C-int::GAL4(21-881)} cassette has been inserted in-frame into the endogenous Nox locus. The presence of the 2A peptide results in the C-int::GAL4(21-881) hemidriver being expressed as a separate protein under the control of endogenous Nox regulatory sequences. The TI{2A-C-int::GAL4(21-881)} cassette was inserted via the CRISPR/Cas-9 drop-in technique. The sgRNA sequence used to target the gene was: AGGGCGTGGCGGGAATCTCC.
