UASp regulatory sequences drive expression of the egl coding sequence. Two silent nucleotide substitutions have been introduced into the coding region (A1599C and G1602C), so that the encoded transcript is not targeted by the shRNA produced by eglGL01170, but the resulting protein is wild-type in sequence. The protein is tagged at the C-terminal end with EGFP.
The mRNA (osk, grk and bcd), protein (stau, Khc, Dynein and BicD) and the oocyte nucleus localization defects as well as the disrupted microtubule network organization observed in stage 10 egg chambers of flies expressing eglGL01170 under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 can be rescued by co-expression of RNAi-resistant eglR.Scer\UAS.P\T.T:Avic\GFP-EGFP.
