Image of Transport Proteins and Eisosomes (IMAGE) University of Groningen Caption Schematic of yeast cell, showing in green-pink the eisosomal structures in which transporters (red, V-shaped) are parked when the substrate is not available for the cell. It also depicts how transporters travel from the endoplasmic reticulum (ER, light grey) to the plasma membrane (dark grey). The top left part of the cell shows trajectories of individual transporters diffusing in the plasma membrane.
