The amino acid replacement R1939X has been introduced into the zip coding region. This mutation corresponds to the disease-associated mutation R1933X in the orthologous human MYH9 gene.

R1939X
Analogous R1933X mutation in human MYH-9 implicated in MYH-9 related disease; mutation carried on in vitro construct.
Flies carrying clones expressing zipR1939X.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4Act.PU in the Johnston's organ display detached scolopidia phenotype although the penetrance is rather low (around 10%).
zipR1933X.Scer\UAS.T:Avic\GFP (expressed using Scer\GAL4sqh.PW) does not show dominant negative activity in a zip1/+ background: the animals complete development and eclose as adult flies simultaneously with their wild-type siblings.
Rho1E3.10/Rho1[+], Scer\GAL4en-e16E, zip2, zipR1939X.UAS.GFP has visible phenotype
Rho1E3.10/Rho1[+], Scer\GAL4en-e16E, zip2, zipR1939X.UAS.GFP has wing phenotype
Rho1E3.10/Rho1[+], Scer\GAL4en-e16E, zip2, zipR1939X.UAS.GFP has leg phenotype
Some adults expressing zipR1933X.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4en-e16E in a zip2/+ ; Rho1E3.10/+ background show both leg and wing abnormalities (14%), while others show wing abnormalities only (4.7%).
Scer\GAL4sqh.PW/zipR1939X.UAS.GFP partially rescues zip2/zip1
Expression of zipR1933X.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4sqh.PW rescues the embryonic lethality of zip1/zip2 animals. 85 +/- 4% of the rescued animals survive to the pupal stage, but no animals survive to the adult stage.
