Profilin

Profilin is a small protein that plays a crucial role in cell movement and shape by regulating the actin cytoskeleton, which is like the cell’s internal framework. It binds to actin, a key structural protein, helping assemble and disassemble actin filaments that enable cells to migrate, divide, and perform various functions. By controlling these filament dynamics, profilin ensures cells adapt their shape and movement as needed, which is vital in processes like healing, immune responses, and development. Its activity is tightly regulated, making it essential for normal cell function and stability.
