Fig. 7. A subset of vacuoles induced by Gas3/PMP22 are coated with actin. NIH3T3
cells were microinjected with HA-Arf6-Q67L, with Gas3/PMP22-GFP or with PH-GFP
and Gas3/PMP22-VSV. 15 hours later cells were fixed and probed with an
antibody to HA and phalloidin (top), with phalloidin (middle), or with an
antibody to VSV and phalloidin (bottom) as shown. (Inset) Enlargement of box
showing differences in actin coating and PIP2 accumulation in
Gas3/PMP22 vacuoles. Bar, 3 µm.
