| molecular function |
|---|
| | GO:0005524 | | ATP binding | | Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| | GO:0016887 | | ATPase activity | | Catalysis of the reaction: ATP + H2O = ADP + phosphate + 2 H+. May or may not be coupled to another reaction. |
| | GO:0008017 | | microtubule binding | | Interacting selectively and non-covalently with microtubules, filaments composed of tubulin monomers. |
| | GO:0003777 | | microtubule motor activity | | Catalysis of movement along a microtubule, coupled to the hydrolysis of a nucleoside triphosphate (usually ATP). |
| | GO:0051010 | | microtubule plus-end binding | | Interacting selectively and non-covalently with the plus end of a microtubule. |
| | GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| biological process |
|---|
| | GO:0032837 | | distributive segregation | | The cell cycle process in which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets during a normally chiasmate meiosis under the condition that chiasma have not occurred between a particular pair of homologs. Distributive segregation is a "backup" mechanism to ensure the segregation of homologs that have failed to cross over - either as a consequence of mutation or not, as, for example, the 4th chromosome of Drosophila melanogaster (which never exchanges, presumably due to its small size) - but nevertheless segregate normally. |
| | GO:0051296 | | establishment of meiotic spindle orientation | | Any process that set the alignment of meiotic spindle relative to other cellular structures. |
| | GO:0007143 | | female meiotic nuclear division | | A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the female germline. |
| | GO:0045132 | | meiotic chromosome segregation | | The process in which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets during M phase of the meiotic cell cycle. |
| | 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:0007052 | | mitotic spindle organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle. |
| | GO:0031116 | | positive regulation of microtubule polymerization | | Any process that activates or increases the frequency, rate or extent of microtubule polymerization. |
| | GO:0007057 | | spindle assembly involved in female meiosis I | | The aggregation, arrangement and bonding together of a set of components to form the spindle during meiosis I of a meiotic cell cycle in females. An example of this is found in Drosophila melanogaster. |
| cellular component |
|---|
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005856 | | cytoskeleton | | Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. |
| | 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. |
