actin filaments

Actin filaments are thin, flexible protein structures found in the cells of all living organisms. They play a crucial role in maintaining cell shape, enabling movement, and facilitating cell division. Actin filaments form part of the cytoskeleton, which provides structural support to cells. They can rapidly grow and shrink, allowing cells to change shape and move, such as during muscle contraction or wound healing. Overall, actin filaments are essential for various cellular processes and help ensure that cells function properly in everything from tissue development to immune responses.
