Figure 6.

Surface MHC I is internalized and gains access to PIP2 vacuoles in cells expressing EFA6 at all times but is only loaded into cells expressing Arf6 Q67L early in transfection. Hela cells were transfected with PH-GFP and EFA6 or Arf6 Q67L. At the indicated time (20 or 44 h), they were allowed to internalize MHC I antibody for 30 min and then were fixed and processed for visualizing internalized antibody.
