Figure 4. Large Hydrophobic Residues Are Crucial for LD Targeting of the M-domain in Cells.
(A) Analysis of the LD-targeting ability of a series of M-domain mutants. Drosophila cells were transfected with mCherry-tagged constructs and incubated 14-18 hours with 0.5 mM oleic acid. LDs were stained with BODIPY. Representative images are shown. Scale bar, 5 μm (merge), 1 μm (inlay).
(B) Quantification of the protein signal on droplets. Data are represented as mean + SD. At least 10 cells were analyzed in each independent experiment.
