Figure S4. Localization of YFP-Rab1 protein in live dividing spermatocytes. from Rab1 interacts with GOLPH3 and controls Golgi structure and contractile ring constriction during cytokinesis in <i>Drosophila melanogaster</i>

Spermatocytes expressing YFP-Rab1 during telophase. Red arrows show YFP-Rab1 localizing to the cleavage furrow. Left panel shows a phase-contrast image of telophase spermatocytes, right panel the corresponding fluorescence image. Scale bar, 10 μm.
