UASp regulatory sequences drive expression of ph-p in which amino acid residues 1398-1484 have been replaced with an 87 amino acid residue random, unstructured sequence ("RLink"). The protein is tagged with Tag:FLAG.
wing disc, with Scer\GAL4en.PU
Expression of ph-pRLink.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4en.PU results in smaller wing discs than normal.
