Fascin (FSCN1)

Organizes filamentous actin into bundles with a minimum of 4.1:1 actin/fascin ratio.

Plays a role in the organization of actin filament bundles and the formation of microspikes, membrane ruffles, and stress fibers. Important for the creation of a diverse set of cell protrusions, such as filopodia, and for cell motility and migration.
