UASp regulatory sequences drive expression of the CTPsyn B isoform (cDNA clone LD27537) which is tagged at the C-terminal end with Venus.
Expression of CTPsynScer\UAS.P\T.B.C.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 does not result in any obvious morphological change in the cytoophidia.
