Summary: 174
Microtubules are dynamic cytoskeletal polymers that assemble
from /-tubulin and are vital for the establishment of cell
polarity, vesicle trafficking and formation of the mitotic/meiotic
spindle. -Tubulin, a protein related to /-tubulin, is required
for initiating the polymerization of microtubules in vivo.
-Tubulin has been found in two main protein complexes: the
-tubulin ring complex and its subunit, the -tubulin small
complex. The latter is analogous to the yeast Tub4 complex. In
the past year, important advances have been made in
understanding the structure and function of the -tubulin ring
complex and how it interacts with microtubules.
