UASt regulatory sequences drive expression of an R518K mutant Hsap\FUS cDNA. In addition, it contains four phenylalanine-to-leucine mutations (amino acids 305, 341, 359 and 368) in the RRM domain of Hsap\FUS.
Expression of Scer\GAL4GMR.PF>Hsap\FUS4F-L.R518K.Scer\UAS does not cause any external eye degeneration.
