Gβ13FScer\UAS.cFa expressed in S2 cells (driven by Scer\GAL4Act5C.PHb) has no effect on the mitotic spindle.
Gβ13FUAS.cFa, Gγ1UAS.cFa, Scer\GAL4VP16.mat.αTub67C has abnormal cytokinesis phenotype
Gβ13FUAS.cFa, Gγ1UAS.cFa, Scer\GAL4VP16.mat.αTub67C has neuroblast & microtubule phenotype
Gβ13FUAS.cFa, Gγ1UAS.cFa, Scer\GAL4Act5C.PHb has spindle phenotype
Simultaneous expression of Gβ13FScer\UAS.cFa and Gγ1Scer\UAS.cFa (driven by Scer\GAL4mat.αTub67C.T:Hsim\VP16) drastically reduced microtubule organisation in the neuroblast. A metaphase mutant neuroblasts form a small symmetric or disorganised spindle, as though both spindle halves are basal. As a result, some telophase neuroblasts undergo equal cleavage, but others also frequently show defective cytokinesis. Gβ13FScer\UAS.cFa and Gγ1Scer\UAS.cFa simultaneously expressed in S2 cells (driven by Scer\GAL4Act5C.PHb) the mitotic spindle becomes shrunken.
