Classification of cytoskeletal molecules. The cytoskeletal molecules can be classified into three main classes, namely the microtubules, microfilaments and intermediate filaments. Within each main class of molecules, it can be further categorised based on its function and molecular type. In addition, there are also other cytoskeletal molecules that do not fall into the above groups, such as the cell adhesion molecules (CAMs) and catenin. Arp, actin-related proteins.
