homology assisted CRISPR knock-in
Engineering MethodHomology assisted CRISPR knock-in (HACK) is an engineering method used in Drosophila to convert existing GAL4 drivers into ShineGAL4 counterparts by replacing GAL4 with a GAL4 DNA-binding domain fused to a Magnet photoswitch. In the cited study, this generated light-responsive transcriptional drivers for optogenetic gene control.
