Amino acid replacement: I209A.
Amino acid replacement: F231A.
UAS regulatory sequences drive expression of exd with a deletion of the polyalanine domain that separates the PBC-A and PBC-C domains. In addition, the key amino acid residues of the nuclear export signal (NES) have been mutated to alanine (amino acid replacements I209A, F213A, I216A and M218A). The protein is tagged at the N-terminal end with Tag:MYC and GFP.
Amino acid replacement: I216A.
Amino acid replacement: M218A.
Expression of exdnes.ΔAla.Scer\UAS.T:Avic\GFP,T:Hsap\MYC under the control of Scer\GAL4Dll-md23 has no effect on distal leg patterning.
