Carries an D204N amino acid substitution in the conserved NAD-binding motif.
Heterozygous CtBP03463 mutant flies carrying two copies of CtBPNAD.T:Zzzz\FLAG show notched wings, while no phenotype is observed when these transgenes are present in a wild-type background or if only one copy of CtBPNAD.T:Zzzz\FLAG is present.
