Recent data have revealed that the tubulin superfamily of proteins is much larger than was thought previously. Six distinct families within the tubulin superfamily have been discovered and more might await discovery. alpha-, beta- and gamma-tubulins are ubiquitous in eukaryotes.

Tubulin as a G-Protein: Regulation of Tubulin-Tubulin Interactions by GTP Hydrolysis
1989As proposed by Hughes in 19831, tubulin belongs to, the large family of GTP-binding proteins, which contains several other subclasses: the elongation and initiation factors of protein synthesis, and proteins involved in signal transduction such as G , G., transducin and the Ras p21 proteins ; recently this family has Deen extended to include low ...

AbstractIntrons of plant tubulin genes are useful molecular tools to study IME (Intron Mediated Enhancement of gene expression) and to define plant genetic and evolutionary relationships through ILP (Intron Length Polymorphism). Here we show that the intron present within the 5′UTR sequence of some rice β‐tubulin genes can sustain IME in rice ...

Tubulin and microtubule structure
Current Opinion in Cell Biology, 1998Our knowledge of microtubule structure and its relationship to microtubule function continue to grow. Cryo-electron microscopy has given us new images of the microtubule polymerization and depolymerization processes and of the interaction of these polymers with motor proteins.

Tubulin has been identified as a membrane component of nerve synaptosomes and myelin, plasma membranes of platelets, thyroid, and tissue culture cells, brain and liver coated vesicles, mitochondria, and in cilia but not flagella of certain molluscs.

The integrity of tubulin molecule is not required for the activity of tubulin carboxypeptidase
Biochemical and Biophysical Research Communications, 1989Tubulin dimer, alpha-tubulin subunit, and C-terminal peptides obtained from the alpha-tubulin subunit were compared in their capabilities to act as substrates of tubulin carboxypeptidase. The results obtained indicate that the enzyme does not require the beta-tubulin subunit to release tyrosine from alpha-tubulin.

Tubulin evolution: Two major types of α-tubulin
Journal of Molecular Evolution, 1982Tubulin subunits have been isolated from a variety of protists and marine invertebrates. The sources were: sperm tails of a tunicate (Ciona intestinalis), an abalone (Haliotis rufescens) and a sea anemone (Tealia crassicornis), the gill cilia of a clam (Mercenaria mercenaria), the cilia of a ciliate (Tetrahymena pyriformis) and the cytoplasm of a slime

Interrelationships of tubulin-GDP and tubulin-GTP in microtubule assembly
Biochemistry, 1987We previously reported that direct incorporation of GDP (i.e., without an initial hydrolysis of GTP) into microtubules occurs throughout an assembly cycle in a constant proportion. The exact proportion varied with reaction conditions, becoming greater under all conditions in which tubulin-GDP increased relative to tubulin-GTP (low Mg2+ and GTP ...

Association of thiocolchicine with tubulin
Biochemical and Biophysical Research Communications, 1989Thiocolchicine, a colchicine analog in which the C-10 methoxy is replaced with a thiomethyl moiety, was shown to bind with high affinity to the colchicine site on tubulin (Ka = 1.07 +/- 0.14 x 10(6) M-1 at 23 degrees C). Like colchicine, the association kinetics were biphasic, and the rate constants of both phases were temperature dependent.

In the mammalian brain, tubulin is the major protein and microtubules are major organelles. Neurite outgrowth, axoplasmic transport and synaptic function are thought to be dependent upon microtubule integrity. Studies of microtubule structure and function relationship, and the control mechanism of tubulin expression shed light on more complicated ...
