Abstract

Actin filament polymerization results primarily from the addition of monomers to pre-existing filaments. Recent studies have revealed that the Arp2/3 protein complex, which includes two actin-related proteins, can nucleate new actin filaments, and this capacity can be enhanced by ActA, a protein used by Listeria to polymerize actin.
