UAS regulatory sequences drive expression of a mutant form of erm containing only the zinc finger domains, fused at the N-terminal end to the Engrailed Repressor Domain (ERD), converting it to act solely as a transcriptional repressor.
UAS regulatory sequences drive expression of a mutant form of erm containing only the zinc finger domains, fused at the N-terminal end to the VP16 activation domain, converting it to act solely as a transcriptional activator.
