Cytoskeleton Types and Their Functions: A Comprehensive Guide
- Microfilaments: These are the thinnest cytoskeletal filaments composed of actin proteins. They function in cell movement, such as muscle contraction and cell crawling.
- Intermediate filaments: These are intermediate in size between microfilaments and microtubules and are composed of various proteins like keratins, vimentin, and lamin. They provide structural support and mechanical strength to cells and tissues.
- Microtubules: These are the largest cytoskeletal filaments composed of tubulin proteins. They form a scaffold within the cell and are involved in various functions like cell division, intracellular transport, and maintaining cell shape.
