beta I + II Tubulin Products

Tubulin is the major building block of microtubules. This intracellular, cylindrical filamentous structure is present in almost all eukaryotic cells. Microtubules function as structural and mobile elements in mitosis, intracellular transport, flagellar movement and the cytoskeleton. Except in the simplest eukaryotes, tubulin exists in all cells as a mixture of similar but not identical sets of alpha and beta tubulin polypeptides. Within either family, individual subunits diverge from each other ...
