UASt regulatory sequences drive expression of an inverted repeat.
Adults expressing Nhe2KK102518 under the control of Scer\GAL4ClC-a.PU present numerous birefringent stones in the Malpighian tubules's lumen.
The expression of Nhe2KK102518 under the control of Scer\GAL4109-30 leads to frequent germarium defects including cyst encapsulation defects and/or disorganized follicular epithelium, loss of germline stem cells, and signs of stalk cells mis-differentiation (i.e. ectopic expression of Eya), as compared to controls. This expression leads to a significant decrease in intracellular pH in pre-follicle and follicle cells within the germarium, as compared to controls.
