What are Intermediate Filaments?
Intermediate filaments are rope-like structures that provide mechanical strength to cells. They are composed of smaller strands in the shape of rods, which are aligned in a staggered array. Intermediate filaments are less dynamic than actin filaments or microtubules, but they work in tandem with these structures to provide support and strength to cells.
There are five types of intermediate filaments: keratin, vimentin, desmin, neurofilaments, and lamins.
The functions of intermediate filaments include:
- Providing mechanical strength to cells
- Anchoring organelles
- Maintaining cell shape
- Preventing cell lysis
Intermediate filaments work with other cytoskeletal filaments, such as actin filaments and microtubules, to provide support and strength to cells.
