Microtubules are the main component of the cell’s internal scaffolding (cytoskeleton). One of their main functions is to transport organelles and proteins required for a cell to move and divide.
While the majority of microtubules originate from a small structure near the nucleus called the centrosome, Irina Kaverina, Ph.D., and colleagues previously identified a unique subset of microtubules that originate from the Golgi complex — a structure inside the cell that processes and packages proteins for transport.
