Amino acid replacement: M647H.
Dominant negative allele.
Expression of Stat92EM647H.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4Mef2.247.Switch specifically during the adult stage (in the presence of RU486) causes a striking defect in long term memory, without affecting anesthesia-resistant memory or short term memory.
Expression of Stat92EM647H.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4ey.PU results in roughening of the eye, a reduction in eye volume and a loss of ventral eye tissue.
