Figure 4.
Plot of squared difference in membrane height versus separation in x-y plane. (Light-orange and dark-orange data) σ = 1.9 kBT/r02; (light-green and dark-green data) σ = 19 kBT/r02. (Dark-colored dots) Results of simulations with no clathrin attached to the membrane. (Light-colored dots) Simulation results with clathrin. The lines are analytical predictions of the equilibrium height fluctuations in the absence of clathrin, as given in Safran (59) and averaged across all orientations between locations in the x-y plane separated by a distance P. Error bars give the standard error of the mean. Simulated data is averaged over 10 independent samples (with clathrin) or five independent samples (without clathrin). (Insets) Fluctuating portions of the membrane with and without clathrin at the two tensions shown in the plot.
