Please explain how the different proteins depicted contribute do F-actin disassembly, assembly or stabilization

F-actin disassembly

The process of breaking down filamentous actin (F-actin) to clear older filaments, providing a pool of actin monomers for polymerization.

Cofilin

A protein that promotes F-actin disassembly by severing actin filaments.

Arp2/3 complex

A protein complex that drives actin nucleation and branching for the growth of new actin filaments.

Tropomyosin

A protein that stabilizes existing F-actin filaments, ensuring their structural integrity.

Actin-severing proteins

Proteins, like gelsolin, that promote F-actin disassembly by cutting filaments into shorter pieces.

Actin-binding proteins

Proteins that bind to F-actin, such as cofilin, causing destabilization and promoting disassembly.

Actin-nucleating proteins

Proteins, like the Arp2/3 complex, that initiate new actin filament growth.

Actin-stabilizing proteins

Proteins, such as tropomyosin, that bind to F-actin to stabilize and prevent disassembly.

Dynamic remodeling

The process that supports structural plasticity during synaptic changes by recycling actin monomers.

Cellular motility

Movement of cells that is regulated by the balance of actin filament assembly and disassembly.
