Arp2/3 complex

The Arp2/3 complex is a group of proteins that play a crucial role in cell movement and shape. It helps assemble actin filaments—structural fibers inside cells—by initiating new branches from existing filaments. This branching creates a dense, web-like network that allows cells to change shape, migrate, and perform various functions. The Arp2/3 complex works like a builder, organizing the actin framework efficiently to support dynamic cellular activities vital for growth, healing, and development.
