Actin and tubulin are two major cytoskeletal proteins found in cells. Actin is a globular protein that polymerizes to form microfilaments, which are crucial for maintaining cell shape, enabling cell movement, and supporting intracellular transport. Actin filaments play a key role in processes like muscle contraction, cytokinesis, and cell division. They interact with myosin to generate contractile forces, especially in muscle cells, facilitating contraction and movement. Tubulin, another important cytoskeletal
