1. Cellular Architecture: Tubb is integral to maintaining the structural integrity of cells. The microtubules formed by tubb provide a scaffold that supports the cell's shape. 2. Intracellular Transport: Microtubules serve as tracks for the movement of organelles and vesicles within the cell. Motor proteins such as kinesin and dynein "walk" along these microtubules, transporting cargo to different cellular compartments. 3. Cell Division: During mitosis, microtubules form the mitotic spindle, which is essential for the segregation of chromosomes into daughter cells. Tubb is crucial for the formation and function of this spindle apparatus.
