UASp regulatory sequences drive expression of the mei-38 coding region which is tagged with three copies of Tag:HA.
mei-38UASp.Tag:HA/Scer\GAL4VP16.nanos.UTR rescues mei-381
Expression of mei-38Scer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 completely rescues the mei-381 nondisjunction phenotype.
