Figure S4.
Colocalization to and translocation from ERESs of COPI-coated membranes. Time-lapse microscopy analysis of living LDLF cells stably expressing ε-COP-YFP (green) cotransfected with Sec24C-mCherry (red) and KDEL-BFP (Blue). Yellow arrows point to ERES labeled with Sec24C, and yellow arrowheads point to COPI membranes moving toward the Golgi (G). Scale bar = 10 µm.
