UAS regulatory sequences drive expression of a mutated form of yki (four point mutations in the WW domain) which is tagged with Tag:V5.
Expression of yki-WW.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4sd-SG29.1 does not result in overgrowth in the wing.
yki-WW.UAS.Tag:V5/Scer\GAL4arm.PS fails to rescue ykiB5
