UASt regulatory sequences drive expression of a mutated form of Hsap\NF2 isoform 1 (contains a deletion of the coding sequence derived from exons 2 and 3), that is tagged at the N-terminal end with Tag:FLAG.
Hsap\NF2Δ2-3.UAS.Tag:FLAG/Scer\GAL4T80 is a non-suppressor of lethal phenotype of Mer4
Scer\GAL4T80 expression of Hsap\NF2Δ2-3.Scer\UAS.T:Zzzz\FLAG (one or two copies) does not suppress lethality (0% rescue) in Mer4/y male flies.
