Microtubules in a sentence

Other microtubules will interact with microtubules from the opposite centrosome: these are called nonkinetochore microtubules or polar microtubules.

Unlike eukaryotic microtubules, bacterial microtubules do not require chaperones to fold. citation In contrast to the 13 protofilaments of eukaryotic microtubules, bacterial microtubules comprise only five.

Although most microtubules have a half-life of 5-10 min, certain microtubules can remain stable for hours.

As a result, microtubules that accumulate this modification are often referred to as Glu-microtubules.

A third type of microtubules, the aster microtubules, radiates from the centrosome into the cytoplasm or contacts components of the membrane skeleton.

However, in most microtubules there is a seam in which tubulin subunits interact α-β. citation Some species of Prosthecobacter also contain microtubules.

In contrast to normal dynamic microtubules, which have a half-life of 5–10 minutes, the captured microtubules can last for hours.

The structure of these bacterial microtubules is similar to that of eukaryotic microtubules, consisting of a hollow tube of protofilaments assembled from heterodimers of bacterial tubulin A (BtubA) and bacterial tubulin B (BtubB).

But microtubules provide more than just mechanical strength; they help prepare the cell for cell division and migration and work as a railway track on which motor proteins transport materials within the cell.

By slowing down microtubules inside growing leaves, spacing them apart and removing them altogether in some experiments, they reveal a system that can independently guide CSCs.

Specifically, the proteins were connected to microtubules, a component of cell “scaffolding” or the cytoskeleton.

Although hemosporidians and piroplasmids have normal triplets of microtubules in their basal bodies, coccidians and gregarines have nine singlets.

Anaphase I Kinetochore microtubules shorten, pulling homologous chromosomes (which consist of a pair of sister chromatids) to opposite poles.

Anti-microtubule agents Vinca alkaloids prevent the assembly of microtubules, whereas taxanes prevent their disassembly.

As this happens, microtubules invade the nuclear space.

Astral microtubules anchor the spindle poles to the cell membrane.

Astral microtubules instead interact with the cytoskeleton near the cell membrane and function in concert with specialized dynein motors.

Both types of pillar cell are characterized by the presence of thousands of cross linked microtubules and actin filaments in parallel orientation.

Cilia and flagella Microtubules have a major structural role in eukaryotic cilia and flagella.

Cilia of eukaryotic cells can also produce chemotaxis; in this case, it is mainly a Ca 2+ -dependent induction of the microtubular system of the basal body and the beat of the 9+2 microtubules within cilia.
