where is tubulin found
10 most extreme places on Earth. A tubulin is a spherical protein, usually found in eukaryotic cells, that comes in many forms, all of which play vital roles in the structure and function of the cell.The alpha and beta forms of these proteins are the basic building blocks of microtubules, one of the main components of a cell's cytoskeleton.he gamma form of the protein is usually found in a cell organelle known as the centrosome, which is a microtubule organization center(MTOC). Ad. The process of polymerization usually takes place in an MTOC, and involves the alpha and beta protein forms binding to a nucleotide known as guanosine triphosphate (GTP).
