Functions of Cytoskeleton

What is Cytoskeleton?

The cytoskeleton is a complex structure that interlinks with the protein of the cell present in the cytoplasm of Prokaryote, Eukaryote, Bacteria, and archaeans. The cytoskeleton is a network of fibers that interlinks all cell organelles and helps the cell to work properly. In eukaryote cells cytoskeleton is a mess of filaments and motor proteins that help in cell motion. Cytoskeletons have the prime function to keep the cell intact and in shape. Cytoskeletons also help in transport. The cytoskeleton is composed of three components. These three components are capable of growth or disassembly dependent on the requirements of the cell....

Cytoskeleton Structure

The cytoskeleton is composed of three types those are:...

Microtubules

These are minute, hollow, and round tubes. Their diameter of about 24 nm. They are hollow and the inner space of microtubules is known as the Lumen. They are formed from soluble tubulin dimers. Soluble tubulin is a heterodimer of alpha-tubulin and beta-tubulin....

Intermediate Filaments

These filaments are about 10 nm in diameter and they provide tensile strength to the cell. They help in the formation of neurofilaments and keratins. There are five types of  Intermediate filaments-...

Microfilaments

These are thread-like protein filaments with a diameter of 3-5 nm. They are specifically present in muscle cells. Microfilaments are composed of subunits of actin protein. Actin protein in these filaments is responsible for muscle contraction. Actin exists in two different forms: globular actin (G-actin) and fibrous actin (G-actin)...
