UASp sequences regulate expression of GFP fused to the Tag:PH(PLCδ-Unk) sequence. This fusion protein can act as a reporter for or to titrate phosphatidylinositol 4,5-bisphosphate within the cell.
Scer\GAL4tub.PU-mediated expression of Avic\GFPPLCδ-PH.Scer\UAS.P\T results in 50% of egg chambers exhibiting nurse cell nuclei in the ooplasm.
