Deletion of sequences encoding shot amino acids 4711 to 4849 (coordinates according to accession number AAF24343). This removes the two EF-hand motifs.
Expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP in embryonic motorneurons or tendon cells in a wild-type background does not engender any obvious dominant negative effects.
shotLA-ΔEF-hand.UAS.GFP/Scer\GAL4sca-537.4 partially rescues shot3/Df(2R)MK1
Scer\GAL4insc-Mz1407/shotLA-ΔEF-hand.UAS.GFP partially rescues shot3
Scer\GAL4insc-Mz1407/shotLA-ΔEF-hand.UAS.GFP partially rescues shot3
Scer\GAL4elav.PU/shotLA-ΔEF-hand.UAS.GFP fails to rescue shotVV/shot3
Scer\GAL4how-24B/shotLA-ΔEF-hand.UAS.GFP fails to rescue shotVV/shot3
The expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP rescues 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 shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP under the control of Scer\GAL4elav.PU fails to rescue the increase in bouton number seen at the neuromuscular junction in shot3/shotVV third instar larvae.
Expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP in motorneurons fails to rescue the dendritic growth phenotype of shotunspecified mutant embryos.
Scer\GAL4sr-md710 driven expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP rescues the shotunspecified tendon cell phenotype.
Scer\GAL4sca-537.4-mediated expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP fully restores the microtubule unbundling and axonal length phenotypes of shot3/Df(2R)MK1 primary neuronal cultures.
Scer\GAL4sca-537.4-mediated expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP fails to fully rescue the reduced filopodia phenotype of shot3/Df(2R)MK1 primary neuronal cultures.
Expression of shotLA-ΔEF-hand.Scer\UAS.T:Avic\GFP under the control of Scer\GAL41407 fails to rescue the motor axon extension defects seen in shot3 mutants. Sensory axon extension is modestly improved over that seen in shot3 mutants.
