Intermediate filaments consist of several intertwined strands of fibrous proteins. Intermediate filaments have no role in cell movement. Their function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place.

They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place. Figure shows how intermediate filaments create a supportive scaffolding inside the cell. The intermediate filaments are the most diverse group Intermediate filaments - YouTube. This lecture explains about the intermediate filaments assembly and structure and function of intermediate filament.http://shomusbiology.com/Download the stu intermediate filaments 1. IFs Summary (LODISH BK. M.B) The association of intermediate filaments with the nuclear and plasma membranes suggests that their principal function is structural. In epithelium, for instance, intermediate filaments provide mechanical support for the plasma membrane where it comes into contact with other cells or with the extracellular matrix. Intermediate filaments this video provides a quick overview of intermediate filament structure and function also it describes how they are physiologically relevant.

Functions of Intermediate Filaments.
Karin ågren-hakala
Intermediate filaments are composed of a family of related proteins sharing common structural and sequence features. Initially designated 'intermediate' because their average diameter is between those of narrower microfilaments and wider myosin filaments found in The function of intermediate filaments is largely mechanical, meaning they provide support for the cell so that other microfilaments can more readily do their transport jobs.
39-3 and 39-8). 2007-06-10 · The best evidence for intermediate filament function comes from observing the consequences of mutation and mis-expression, primarily in human tissues. Mostly these observations suggest that intermediate filaments are important in allowing individual cells, the tissues and whole organs to cope with various types of stress, in health and disease.

The most common intermediate filament comprising the cytoskeleton is vimentin, a type III intermediate filament that regulates the F-actin and microtubule filament systems along with cell signaling, motility, structure, and adhesion during interphase and mitosis and whose assembly, disassembly, binding partners (14-3-3 and Beclin 1), and function are regulated by a variety of post Intermediate filaments provide scaffolding for the cell and protect it against stress.
Our interest in the structure and function of intermediate filament proteins was initiated approximately 7 years ago while working on the regulation of
IFs are often a major component of the cell and are most prominent in the cells of vertebrates.
For this reason, there is a wide variety of intermediate filaments in different types of cells. The tight association between protofilaments provide intermediate filaments with a high tensile strength. This makes them the most stable component of the cytoskeleton. Intermediate filaments are therefore found in particularly durable structures such as hair, scales and fingernails. Glial filaments (in astrocytes) Neurofilaments (in nerve cells) Vimentin (in many types of cells) Desmin (in muscle fibers). Functions of intermediate filaments.
