| molecular function |
|---|
| | GO:0008017 | | microtubule binding | | Interacting selectively and non-covalently with microtubules, filaments composed of tubulin monomers. |
| | GO:0051010 | | microtubule plus-end binding | | Interacting selectively and non-covalently with the plus end of a microtubule. |
| | GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| | GO:0042803 | | protein homodimerization activity | | Interacting selectively and non-covalently with an identical protein to form a homodimer. |
| | GO:0005200 | | structural constituent of cytoskeleton | | The action of a molecule that contributes to the structural integrity of a cytoskeletal structure. |
| 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:0007019 | | microtubule depolymerization | | The removal of tubulin heterodimers from one or both ends of a microtubule. |
| | GO:0007020 | | microtubule nucleation | | The process in which tubulin alpha-beta heterodimers begin aggregation to form an oligomeric tubulin structure (a microtubule seed). Microtubule nucleation is the initiating step in the formation of a microtubule in the absence of any existing microtubules ('de novo' microtubule formation). |
| | 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:0031578 | | mitotic spindle orientation checkpoint | | 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. |
| | GO:0007026 | | negative regulation of microtubule depolymerization | | 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. |
| | GO:0030473 | | nuclear migration along microtubule | | The directed movement of the nucleus along microtubules within the cell, mediated by motor proteins. |
| | GO:0031116 | | positive regulation of microtubule polymerization | | Any process that activates or increases the frequency, rate or extent of microtubule polymerization. |
| cellular component |
|---|
| | 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: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: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:0005819 | | spindle | | 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. |
| | GO:0051233 | | spindle midzone | | The area in the center of the spindle where the spindle microtubules from opposite poles overlap. |
| | GO:0000922 | | spindle pole | | 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. |
| | GO:0005816 | | spindle pole body | | The microtubule organizing center in fungi; functionally homologous to the animal cell centrosome. |
