| 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:0007049 | | cell cycle | | The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division. |
| | GO:0051301 | | cell division | | The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells. |
| | GO:0007059 | | 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. In eukaryotes, chromosome segregation begins with the condensation of chromosomes, includes chromosome separation, and ends when chromosomes have completed movement to the spindle poles. |
| | GO:0030951 | | establishment or maintenance of microtubule cytoskeleton polarity | | Any cellular process that results in the specification, formation or maintenance of polarized microtubule-based cytoskeletal structures. |
| | GO:0007019 | | microtubule depolymerization | | The removal of tubulin heterodimers from one or both ends of a microtubule. |
| | 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:0007080 | | mitotic metaphase plate congression | | The cell cycle process in which chromosomes are aligned at the metaphase plate, a plane halfway between the poles of the mitotic spindle, during mitosis. |
| | GO:0051983 | | regulation of chromosome segregation | | Any process that modulates the frequency, rate or extent of chromosome segregation, the process in which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets. |
| cellular component |
|---|
| | GO:0005694 | | chromosome | | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| | GO:0000775 | | chromosome, centromeric region | | The region of a chromosome that includes the centromeric DNA and associated proteins. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome. |
| | GO:0000777 | | condensed chromosome kinetochore | | A multisubunit complex that is located at the centromeric region of a condensed chromosome and provides an attachment point for the spindle microtubules. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005881 | | cytoplasmic microtubule | | Any microtubule in the cytoplasm of a cell. |
| | 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:0000776 | | kinetochore | | A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | 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:0015630 | | microtubule cytoskeleton | | The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins. |
| | GO:0035371 | | microtubule plus-end | | 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. |
| | 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. |
