Localization of AcGFP-BmVasa and mCherry-BmDcp2 in BmN4 cells. Line scans (white line in the enlarged region) show that both wild type and ATPase mutant BmVasa-E339Q do not colocalize with BmDcp2. Line scans of fluorescence intensity are normalized to the highest value and depicted at the right panel. Scale bar 4 μm.
