tubulin
The cytoskeleton is primarily made up of three types of protein filaments: microfilaments (composed of actin), intermediate filaments (various proteins like keratin), and microtubules (comprised of tubulin). These filaments provide structural support, shape, and aid in intracellular transport within the cell.
Microtubules typically radiate outwards from the centre of the cell; a place called an MTOC or microtubule organizing centre. They are involved in kinetichore and spindle formation during mitosis. On the other hand actin filaments are found in the cell cortex just below the cell membrane and are involved in cell locomotion.
it is buit by tubulin protiens.there are two types of tubulin protien. they are 1.alpha 2.beeta. they are very use full in cell devision.and they help to built cytosceleton.
microtubules and microfilaments are alike in some ways, but are NOT the same. Microtubules are the building blocks to actin and provide structure and cell strength. They are thinner in relation to microtubules. Microtubules are made from tubulin, and are seen in different cell function, such as mitosis (extend from centrosomes to attach to centromere kinetechore), reproductive system (making up flagella that move sperm or cilia in fallopian tubes to catch/move the egg) and respiratory system (cilia in the lungs to remove debris and keep lungs clean).
Microtubules are polymers of tubulin. Microfilaments are polymers of actin.
Microtubules (actin and tubulin) are cytoskeleton of eukaryote (and not prokaryote). Prokaryote do have cytoskeleton system such as FtsZ.
Actin and microtubules are distinct structures within the cell. Actin is a protein that forms thin filaments, while microtubules are made of tubulin proteins and form a network of hollow tubes. Both actin and microtubules play important roles in cell structure and movement.
C. Centrioles are found in the microtubule organizing centers of plants.

Cytoskeletal filaments are made up of actin, intermediate filaments that contain 70 different proteins coupled with microtubules with tubulin as the basic subunit.
The three protein fibers found in the cytoskeleton are actin filaments (microfilaments), intermediate filaments, and microtubules. They play key roles in providing structure and support to the cell, facilitating cell movement, and aiding in cell division and intracellular transport.
tubulin
Microtubules are made of protein subunits called tubulin. These tubulin subunits polymerize to form long, hollow tubular structures that are essential for various cellular processes such as cell division, cell shape maintenance, and intracellular transport.
disassemble
Microtubules are made up of repeating units called tubulin. Tubulin is a protein that assembles into a structure that forms the walls of the microtubule, providing structure and stability. The tubulin units polymerize to form the long, hollow structures of microtubules essential for various cellular processes like cell division and intracellular transport.
The cytoskeleton is primarily made up of three types of protein filaments: microfilaments (composed of actin), intermediate filaments (various proteins like keratin), and microtubules (comprised of tubulin).
