Binds directly to F-actin and induces actin filament bundling. May function as a regulator of actin filament organization. Colocalized with actin in the oral apparatus in interphase cells. In dividing cells colocalized with actin in the division furrow. The N-terminus is blocked. On the 2D-gel the determined pI of this protein is: 7.5, its MW is: 71 kDa. To yeast fimbrin.
