formin family members have two adjacent domains:

FH1- rich in proline, landing site for profilin–ATP–G-actin

FH2 - form a dimer and nucleate filament assembly

Two major classes of actin-nucleating proteins:

1. Formins nucleate the assembly of unbranched filaments 

2. Arp2/3 complex nucleates the assembly of branched actin networks
