Homologous recombination was used to replace the starting codon of all 27 Drosophila Rab proteins with EYFP and myc resulting in expression of Rab proteins tagged with EYFP and myc at the N-terminus. For more information, see Dunst et al., 2015.
See the UAS-Rab page for insertions expressing wild-type, dominant-negative and constitutively-active YFP-tagged Rab proteins under the control of UAS.
