Study Notes
The Importance of the Cytoskeleton in Cell Function
- The cytoskeleton is essential for white blood cells to engulf pathogens and for cells to move throughout the body.
- Organelles within cells are dynamic structures that grow, divide, and are recycled, requiring spatial rearrangement within the cell.
- The cytoskeleton is crucial for cell division, allowing for organelle rearrangement and genetic material division.
- It consists of protein fibers (microfilaments, intermediate filaments, and microtubules) and motor proteins (kinesins, dyneins, and myosins).
- Protein fibers like actin and tubulin are the smallest and largest components of the cytoskeleton, respectively.
- Intermediate filaments, such as keratin and laminin, are important for cell structure and support.
- Motor proteins, fueled by cellular energy (ATP), move along cytoskeletal filaments to transport materials within the cell.
- Dysfunction in cytoskeletal proteins can lead to diseases like ALS and blistering diseases, emphasizing the importance of the cytoskeleton in the body.
- Toxins like taxol can affect the cytoskeleton, preventing processes like cell division and are used in cancer treatment.
- The cytoskeleton is crucial not only in animal cells but also in plants, playing a role in processes like cytoplasmic streaming.
- Cytoplasmic streaming, facilitated by the cytoskeleton, is important for transporting organelles and molecules in the cell.
- Prokaryotes also have homologous proteins to the eukaryotic cytoskeleton, such as FtsZ (similar to tubulin) and MreB/Mbl (similar to actin).
