UASt regulatory sequences drive expression of a mutated Gαo cDNA (carries the amino acid replacement Q205L).
neuroblast, with Scer\GAL4VP16.mat.αTub67C
Overexpression of G-oα47AQ205L.Scer\UAS under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 results in 2% of neuroblasts exhibiting equal-size divisions, with no defects in spindle geometry.
