Tubulins

Tubulins are a family of proteins found in all eukaryotic cells that form part of the cytoskeleton. They are responsible for the assembly of microtubules, which are long hollow tubes made of tubulin proteins that provide structural integrity to the cell and allow intracellular transport of molecules. Microtubules also play a key role in processes such as cell division and organelle trafficking. Tubulins are essential for the functioning of cellular structures and enable cells to respond to their environment and perform their specialized functions. In addition, tubulins are also involved in the assembly of other cell structures, including the cilia and flagella which are used for motility in some organism.
