Microtubules (micro- + tube + -ule) are a component of the cytoskeleton, found
throughout the cytoplasm. These tubular polymers of tubulin can grow as long as
Microtubules - Thick Protein Tubes. Microtubules are usually discussed with
microfilaments. Although they are both proteins that help define cell structure and
The cytoskeleton gives cells structure and shape and allows them to move
around. It's also important for intracellular transport. Learn about...
A microtubule is a polymer of globular tubulin subunits, which are arranged in a
cylindrical tube measuring 24 nm in diameter — more than twice the width of an ...

An a,b-tubulin heterodimer is the basic structural unit of microtubules. The
heterodimer does not come apart, once formed. The a and b tubulins, which are
Microtubules are hollow, fibrous shafts whose main function is to help support

Microtubules. These straight, hollow cylinders are found throughout the
cytoplasm of all eukaryotic cells (prokaryotes don't have them) and carry out a

In most cell types, thirteen protofilaments associate laterally to form a microtubule
. In a few cases microtubules contain more or fewer protofilaments .
