UASt regulatory sequences drive expression of a mutated Hsap\LIN28A open reading frame that contains substitutions in the CSD motif (W46A, F55A and F73A) and CCHC motif (H147A and H169A). The coding sequence is tagged with Tag:HA.
Expressing Hsap\LIN28Amut.UAS.Tag:HA under the control of Scer\GAL4GMR.PU does not induce any obvious eye defects, as compared to controls.
