UAS regulatory sequences drive expression of Mmus\Icam5 in which the mCherry tag has been inserted between the transmembrane domain and the extracellular domain.
Animals co-expressing Syt1Scer\UAS.T:Avic\GFP-EGFP and Mmus\Icam5Scer\UAS.T:Disc\RFP-mCherry under the control of Scer\GAL4elav.PU have normal electroretinogram responses and show normal climbing ability in a negative geotaxis assay.
