Publisher Summary This chapter discusses the regulation of microtubules in Tetrahymena. A
combined approach, using both in vivo and in vitro studies, will probably be required to …

The microtubule cytoskeleton is assembled from the α-and β-tubulin subunits of the
canonical tubulin heterodimer, which polymerizes into microtubules, and a small number of …

The discovery of δ-tubulin, the fourth member of the tubulin superfamily, in Chlamydomonas
[1] has led to the identification in the genomes of vertebrates and protozoa of putative δ …

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 …

Microtubules are organized into diverse cellular structures in multicellular organisms. How is
such diversity generated? Although highly conserved overall, variable regions within α‐and …

The ciliated protozoan Paramecium harbours a particularly large diversity of microtubule
networks, ranging from the elaborate and stable ciliary axonemes and basal bodies to very …

Two new studies show that e tubulin is required for centriole/basal body duplication in both
Chlamydomonas and Paramecium, adding to the list of new tubulin family members …

Publisher Summary Centrosomes are the major microtubule organizing centers (MTOCs) in
animal cells. They consist of two structural components: the centriole, which is composed of …

Microtubules are long, slender polymers of αβ-tubulin found in all eukaryotic cells. Tubulins
associate longitudinally to form protofilaments, and adjacent protofilaments associate …

Microtubules are hollow tubes some 25 nm in diameter participating in the eukaryotic
cytoskeleton. They are built from αβ-tubulin heterodimers that associate to form …
