UASt regulatory sequences drive expression of an inverted repeat.
Expression of unc-13-4AKK102198 driven by Scer\GAL4phm.PO does not lead to developmental delay/arrest at the larval stage.
Knockdown of unc-13-4A, through expression of unc-13-4AKK102198 under the control of Scer\GAL4hs.2sev or Scer\GAL4GMR.PU does not affect ommatidial rotation.
Knockdown of unc-13-4A, through expression of unc-13-4AKK102198 under the control of Scer\GAL4hs.2sev enhances the nmoScer\UAS.cUa-induced eye phenotype.
