Protein trap insertion line, in-frame.
Knockdown of expression of the trol protein produced in trolCPTI002049 flies (using Avic\GFPdsRNA.shRNA.Scer\UAS.3 expressed under the control of Scer\GAL4SPARC-MI00329-GAL4 to target the YFP-tagged trol mRNA) results in hyperconstriction of the tissue in the wing disc.
