UAS regulatory sequences drive expression of a short inverted repeat.
Expression of Sox21aHMJ21395 under the control of Scer\GAL4Su(H).GBE (in combination with tub-Gal80[ts]) leads to increased number of pH3-positive cells per adult gut compared to controls.
Expression of Sox21aHMJ21395 under the control of Scer\GAL4Su(H).GBE (using GAL80ts for temporal control) induces rapid accumulation of enteroblast-like cells in the intestinal epithelium.
Expression of Sox21aHMJ21395 in enteroblasts under the control of Scer\GAL4Su(H).GBE (limited to the adult stages using Scer\GAL80ts.αTub84B) leads to accumulation of enteroblasts. Flanking enterocytes are eliminated by delamination into the lumen. Enteroblasts are also found intercalated with enterocytes.
