Beta Tubulin is a protein that plays a crucial role in the structure and function of microtubules, which are essential components of the cytoskeleton in eukaryotic cells. It is one of the two subunits that make up tubulin, the other being Alpha Tubulin. Together, these subunits polymerize to form microtubules, providing support and shape to the cell, as well as facilitating intracellular transport. Microtubules, composed of Beta Tubulin and Alpha Tubulin, are involved in various cellular processes, including cell division, motility, and maintaining cell shape. They also serve as tracks for motor proteins, such as Kinesin and Dynein, which transport cellular cargo along the microtubules. Understanding Beta Tubulin is important for studying cell biology and the mechanisms of diseases, including cancer.
