Profilin has multiple roles in cellular activities:
Actin Polymerization: Profilin accelerates the addition of actin monomers to the growing ends of actin filaments, thereby regulating cytoskeletal dynamics. Cell Motility: By regulating actin dynamics, profilin is crucial for cell movement and migration. Signal Transduction: Profilin interacts with several signaling molecules, linking signal transduction pathways to actin cytoskeletal reorganization. Endocytosis and Exocytosis: Profilin is involved in vesicle trafficking processes, including endocytosis and exocytosis.
