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

PTS1 signals are recognized by the peroxin Pex5 receptor

PTS2 signals are recognized by the peroxin Pex7 receptor

Neither targeting sequence is cleaved after import.
