UAS regulatory sequences drive expression of full-length peb in which zinc finger cluster 9 has been mutated.
peb9mut.UAS.EGFP/Scer\GAL4Sgs3.PD partially rescues peb1142
Expression of peb9mut.Scer\UAS.T:Avic\GFP-EGFP driven by Scer\GAL4Sgs3.PD almost fully rescues failure of germ band retraction in peb1142/y mutant embryos.
