Figure 4.

Time profiles of actin density field reveal altered network organization leading to actin fragmentation at elevated Arp2/3 concentrations. At various time points in our simulations with different Arp2/3 concentrations, representative snapshots are converted into actin density fields to reveal actin organization. The actin density field is visualized at a 40-μM threshold concentration in each case. The voxels that have a local actin concentration higher than the threshold concentration are shown in red. Timestamp in seconds is shown to the top, while Arp2/3 concentrations are mentioned on the left. Data shown here are from the final snapshot of a single replicate corresponding to each [Arp2/3].
