Deletion of sequences encoding shot amino acids 4859 to 4905 (coordinates according to accession number AAF24343). This removes most of the GAS2 motif.
shotLC-ΔGAS2.UAS.GFP/Scer\GAL4pnr.PU fails to rescue shotSF20
shotLC-ΔGAS2.UAS.GFP/Scer\GAL4en.PU fails to rescue shotSF20
shotLC-ΔGAS2.UAS.GFP/Scer\GAL4btl.PS fails to rescue shot3
The expression of shotLC-ΔGAS2.Scer\UAS.T:Avic\GFP fails to rescue both the increased length:width ratio of the dorsal hole (expression under the control of Scer\GAL4pnr.PU) and the abnormal microtubules of the dorsal-most epithelial cells (expression under the control of Scer\GAL4en.PU) observed during dorsal closure of shotSF20 homozygous embryos.
Expression of shotLC-ΔGAS2.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4btl.PS fails to rescue lumen formation in the tracheal dorsal trunk and at the dorsal midline in shot3 embryos.
