UASp regulatory sequences drive expression of a mutant Tl polypeptide carrying a single amino acid change resulting in a form that constitutively signals independent of ligand binding and tagged with GFP.
abnormal dorsal/ventral axis specification | maternal effect, with Scer\GAL4VP16.mat.αTub67C
lethal | maternal effect, with Scer\GAL4VP16.mat.αTub67C
Embryos derived from mothers expressing Tl10b.Scer\UAS.P\T.T:Avic\GFP under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 fail to hatch and are ventralised.
