Figure 11.16Organization of microvilli

The core actin filaments of microvilli are crosslinked into closely packed bundles by fimbrin and villin. They are attached to the plasma membrane along their length by lateral arms, consisting of myosin I and calmodulin. The plus ends of the actin filaments are embedded in a cap of unidentified proteins at the tip of the microvillus.
