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 are filamentous intracellular structures that are responsible for
various kinds of movements in all eukaryotic cells. Microtubules are involved in ...
Microtubules are usually discussed with microfilaments. Although they are both
proteins that help define cell structure and movement, they are very different ...
The cytoskeleton gives cells structure and shape and allows them to move
around. It's also important for intracellular transport. Learn about...
Dynamic networks of protein filaments give shape to cells and power cell
movement. Learn how microtubules, actin filaments, and intermediate filaments ...
Microtubules, the third principal component of the cytoskeleton, are rigid hollow
rods approximately 25 nm in diameter. Like actin filaments, microtubules are ...
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 ...
Microtubules in neurons consist of highly dynamic regions as well as stable
regions, some of which persist after bouts of severing as short mobile polymers.
Summary of the main functions of microtubules together with basic information
about the structure of microtubules that explains how they provide their main ...
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
