| biological process |
|---|
| | GO:0034613 | | cellular protein localization | | 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. |
| | GO:0000742 | | karyogamy involved in conjugation with cellular fusion | | 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. |
| | GO:0008152 | | metabolic process | | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
| | GO:0034631 | | microtubule anchoring at spindle pole body | | Any process in which a microtubule is maintained in a specific location in a cell by attachment to a spindle pole body. Microtubules attach to spindle pole bodies at the minus end. |
| | GO:0001578 | | microtubule bundle formation | | A process that results in a parallel arrangement of microtubules. |
| | GO:0007018 | | microtubule-based movement | | A microtubule-based process that results in the movement of organelles, other microtubules, or other cellular components. Examples include motor-driven movement along microtubules and movement driven by polymerization or depolymerization of microtubules. |
| | GO:1990758 | | mitotic sister chromatid biorientation | | The mitotic cell cycle process in which sister chromatids establish stable, end-on attachments to the plus ends of microtubules emanating from opposite spindle poles, oriented such that separation can proceed. This is the final step in metaphase plate congression. |
| | GO:0007064 | | mitotic sister chromatid cohesion | | 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. |
| | GO:0000070 | | mitotic sister chromatid segregation | | The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets. |
| | GO:0090307 | | mitotic spindle assembly | | The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of mitosis. |
| | GO:0000743 | | nuclear migration involved in conjugation with cellular fusion | | The microtubule-based movement of nuclei towards one another as a prelude to karyogamy in organisms undergoing conjugation with cellular fusion. |
| | GO:0060236 | | regulation of mitotic spindle organization | | Any process that modulates the rate, frequency or extent of the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle. |
| cellular component |
|---|
| | GO:1990811 | | Msd1-Wdr8-Pkl1 complex | | A protein ternary complex that anchors microtubule minus ends to mitotic spindle pole bodies. The founding complex contains a microtubule anchoring protein (Msd1 in fission yeast), A WD-repeat Wdr8 family protein and and a minus end-directed kinesin. |
| | GO:0000778 | | condensed nuclear chromosome kinetochore | | A multisubunit complex that is located at the centromeric region of a condensed nuclear chromosome and provides an attachment point for the spindle microtubules. |
| | GO:0005881 | | cytoplasmic microtubule | | Any microtubule in the cytoplasm of a cell. |
| | GO:0005871 | | kinesin complex | | Any complex that includes a dimer of molecules from the kinesin superfamily, a group of related proteins that contain an extended region of predicted alpha-helical coiled coil in the main chain that likely produces dimerization. The native complexes of several kinesin family members have also been shown to contain additional peptides, often designated light chains as all of the noncatalytic subunits that are currently known are smaller than the chain that contains the motor unit. Kinesin complexes generally possess a force-generating enzymatic activity, or motor, which converts the free energy of the gamma phosphate bond of ATP into mechanical work. |
| | GO:0005874 | | microtubule | | Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle. |
| | GO:0005875 | | microtubule associated complex | | Any multimeric complex connected to a microtubule. |
| | GO:0072686 | | mitotic spindle | | A spindle that forms as part of mitosis. Mitotic and meiotic spindles contain distinctive complements of proteins associated with microtubules. |
| | GO:0044732 | | mitotic spindle pole body | | The microtubule organizing center that forms as part of the mitotic cell cycle; functionally homologous to the animal cell centrosome. |
| | GO:0005634 | | nucleus | | 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. |
| | GO:0005816 | | spindle pole body | | The microtubule organizing center in fungi; functionally homologous to the animal cell centrosome. |
