What is the Cytoskeleton?
The cytoskeleton is a dynamic network of protein filaments and tubules that provide structural support, shape, and intracellular organization to eukaryotic cells. It plays crucial roles in various cellular processes, including:
- Maintaining cell shape and rigidity
- Facilitating cell movement through interactions with motor proteins
- Providing tracks for intracellular transport
- Facilitating cell division and organelle segregation
- Regulating cell signaling and metabolism
The cytoskeleton is composed of three main types of filaments:
- Microtubules: Long, hollow tubes made of tubulin proteins that form the main structural framework of the cell.
- Microfilaments (actin filaments): Solid, long, thin filaments made of actin proteins that are involved in cell movement and contractile functions.
- Intermediate filaments: Tough, fibrous filaments made of various proteins that provide additional structural support and resistance to mechanical stress.
