The removal of tubulin heterodimers from one or both ends of a microtubule.

Any process that stops, prevents, or reduces the frequency, rate or extent of microtubule depolymerization; prevention of depolymerization of a microtubule can result from binding by 'capping' at the plus end (e.g. by interaction with another cellular protein of structure) or by exposing microtubules to a stabilizing drug such as taxol.

The cell cycle process in which the sister chromatids of a replicated chromosome are joined along the entire length of the chromosome, from their formation in S phase through metaphase during a mitotic cell cycle. This cohesion cycle is critical for high fidelity chromosome transmission.

The cell cycle process in which the sister chromatids of a replicated chromosome are joined along the entire length of the chromosome, from their formation in S phase through metaphase during a mitotic cell cycle. This cohesion cycle is critical for high fidelity chromosome transmission.

The directed movement of the nucleus along microtubules within the cell, mediated by motor proteins.

The process in which copies of the 2-micrometer plasmid, found in fungi such as Saccharomyces, are distributed to daughter cells upon cell division.

The process in which copies of the 2-micrometer plasmid, found in fungi such as Saccharomyces, are distributed to daughter cells upon cell division.

Any process that activates or increases the frequency, rate or extent of microtubule polymerization.

A cell cycle checkpoint that monitors and signals errors in the placement or orientation of the spindle in the cell. This delays the completion of anaphase until errors are corrected.

A process in which a protein is transported to, or maintained in, a location at a microtubule plus-end.

During sexual reproduction, the creation of a single nucleus from multiple nuclei as a result of fusing the lipid bilayers that surround each nuclei. This occurs after cytogamy.

The microtubule-based movement of nuclei towards one another as a prelude to karyogamy in organisms undergoing conjugation with cellular fusion.

Oscillatory movement of the nucleus involved in meiosis I. This oscillatory movement is led by an astral microtubule array emanating from the spindle pole body, and driven by the microtubule motor cytoplasmic dynein.

Any process that modulates the frequency, rate or extent of microtubule polymerization or depolymerization by the addition or removal of tubulin heterodimers from a microtubule.

Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell.

A process in which a protein is transported to, or maintained at, a microtubule.

A process in which a protein is transported to, or maintained at, a microtubule.

The cell cycle process in which spindle microtubules become physically associated with the proteins making up the kinetochore complex as part of mitotic metaphase plate congression.

The cell cycle process in which spindle microtubules become physically associated with the proteins making up the kinetochore complex as part of mitotic metaphase plate congression.

The specification and formation of bipolar intracellular organization or cell growth patterns. Bipolar organization is the organization that is a mirror image along an axis from a plane.

The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of mitosis.

A process in which a protein is transported to, or maintained in, a location at a microtubule plus-end.

Any process in which a gamma-tubulin complex is transported to, or maintained in, a specific location at a mitotic spindle pole body.

Any microtubule in the cytoplasm of a cell.

Either of the ends of a spindle, where spindle microtubules are organized; usually contains a microtubule organizing center and accessory molecules, spindle microtubules and astral microtubules.

The array of microtubules and associated molecules that forms between opposite poles of a eukaryotic cell during mitosis or meiosis and serves to move the duplicated chromosomes apart.

The growing (plus) end of a microtubule. In vitro, microtubules polymerize more quickly at the plus end than at the minus end. In vivo, microtubule growth occurs only at the plus end, and the plus end switches between periods of growth and shortening, a behavior known as dynamic instability.

The area in the center of the spindle where the spindle microtubules from opposite poles overlap.

Any of the spindle microtubules that radiate in all directions from the spindle poles and are thought to contribute to the forces that separate the poles and position them in relation to the rest of the cell.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

Any microtubule in the nucleus of a cell.

The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.

The microtubule organizing center that forms as part of the mitotic cell cycle; functionally homologous to the animal cell centrosome.

The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.

Arrays of microtubules underlying and connected to the plasma membrane in the cortical cytosol.

Any of the mitotic spindle microtubules that radiate in all directions from the spindle poles and are thought to contribute to the forces that separate the poles and position them in relation to the rest of the cell.

The area in the center of the anaphase spindle consisting of microtubules, microtubule bundling factors and kinesin motors where the spindle microtubules from opposite poles overlap in an antiparallel manner.
