Expression of zfh1 coding sequence with altered CtBP interacting domain is governed by UAS regulatory sequences. In the CtBP interacting domain PLDLS at nucleotides 2374 to 2388 (CGCTGGACTTGTCC) was changed to ASASA. Amino acid replacement: P?A. Amino acid replacement: L?S. Amino acid replacement: D?A. Amino acid replacement: L?S. Amino acid replacement: S?A.
Expression of zfh1CIDm.Scer\UAS under the control of Scer\GAL4A3.eya (restricted to adult stages using Scer\GAL80ts.αTub84B) does not induce accumulation of excess early-stage cells.
