Summary
Three dimensional microtubule map floating on a raw electron micrograph.
Microtubules play important roles in eukaryotic cell morphogenesis, organelle transport, and mitosis. During mitosis, the microtubule network is restructured to form the mitotic apparatus. This requires considerable dynamics of the microtuble. Interaction between the component tubulin molecules is the key to understanding this dynamic property. In the 8Å resolution 3D map determined by cryo-EM and single particle image analysis, tubulin secondary structures, such as alpha helices, are well defined. This warrants an accurate positioning of the tubulin atomic structures into the microtubule map, and provides unambiguous information about the intermolecular interactions.
