Polymerization of tubulin
Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm and have an inner diameter between 11 and 15 nm. They are formed by the polymerization of a dimer of two globular proteins, alpha and beta tubulin into protofilaments that can then associate laterally to f… WebApr 1, 1990 · Sites of Tubulin Polymerization in PC 12 Cells. The site at which tubulin enters into polymer in the neuritic process is a very important datum in terms of our …
