Filopodia are highly dynamic cell-surface protrusions used by cells to sense their external environment. At the core of the filopodium is a bundle of actin filaments. These give form to the filopodia and also drive the cycle of elongation and retraction. Recent studies have shown that two very different actin nucleating proteins control the formation of filopodial actin filaments - Arp2/3 and Formins. Although the actin filaments produced by these two nucleators have very different structures and properties, recent work has begun to piece together evidence for co-operation between Arp2/3 and formins in filopodia formation, leading to a deeper understanding of these sensory organelles.
