Native Bovine gelsolin is a calcium and polyphosphoinositide regulated actin-binding protein which consists of 6 homologous domains. It is involved in cell morphology, motility, growth and apoptosis. Gelsolin affects filament assembly by severing actin filaments, forming a nucleus for polymerisation, and capping the fast exchanging end of the filaments.
