... background. The 3′ UTR is essential for accumulation of these RNAs into the pole plasm and pole cells. All images scale bar=50 µm. Fig. 3. Bsg25D RNA contains localization elements within the coding region and 3′ UTR. (A) Schematic diagram of the transgenic constructs used, eGFP (green), Bsg25D-PB coding...

... of transposon-encoded mRNAs, translational activation of gurken ( grk ) mRNA, and completion of oogenesis itself. Vas protein accumulates in the perinuclear nuage in nurse cells soon after their specification, and then at stage 10 Vas translocates to the posterior pole plasm of the oocyte. We produced a series...
