Microtubules

Caption

Rice University scientists are using custom software to help explain the dynamic instability seen at all times in microtubules, essential elements of a cell's cytoskeleton. The individual elements are protein dimers attached to either guanosine triphosphate (GTP) in red or guanosine diphosphate (GDP) in blue. Clusters of GTP-binding molecules serve as caps that slow or stop microtubules from dissolving.
