| | GO:0003779 | | actin binding | | Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments. |
| | GO:0005516 | | calmodulin binding | | Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states. |
| | 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). |
| biological process |
|---|
| | GO:1903478 | | actin filament bundle convergence involved in mitotic contractile ring assembly | | Any actin filament bundle convergence that is involved in mitotic actomyosin contractile ring assembly. |
| | GO:0000917 | | barrier septum assembly | | The assembly and arrangement of a septum that spans the plasma membrane interface between progeny cells following cytokinesis. The progeny cells that form a barrier septum are not able to exchange intracellular material. |
| | 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:1903475 | | mitotic actomyosin contractile ring assembly | | Any actomyosin contractile ring assembly that is involved in mitotic cytokinesis. |
| | GO:1903479 | | mitotic actomyosin contractile ring assembly actin filament organization | | Any actin filament organization that is involved in mitotic actomyosin contractile ring assembly. |
| | GO:1902405 | | mitotic actomyosin contractile ring localization | | Any actomyosin contractile ring localization that is involved in mitotic cell cycle. |
| | GO:1903477 | | mitotic contractile ring actin filament bundle assembly | | Any actin filament bundle assembly that is involved in mitotic actomyosin contractile ring assembly. |
| | GO:0000281 | | mitotic cytokinesis | | A cell cycle process that results in the division of the cytoplasm of a cell after mitosis, resulting in the separation of the original cell into two daughter cells. |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | GO:0071574 | | protein localization to medial cortex | | A process in which a protein is transported to, or maintained in, the medial cortex. |
| | GO:0043087 | | regulation of GTPase activity | | Any process that modulates the rate of GTP hydrolysis by a GTPase. |
| | GO:0007165 | | signal transduction | | The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. |
| | GO:0007264 | | small GTPase mediated signal transduction | | Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals. |
| cellular component |
|---|
| | GO:0005826 | | actomyosin contractile ring | | A cytoskeletal structure composed of actin filaments and myosin that forms beneath the plasma membrane of many cells, including animal cells and yeast cells, in a plane perpendicular to the axis of the spindle, i.e. the cell division plane. Ring contraction is associated with centripetal growth of the membrane that divides the cytoplasm of the two daughter cells. In animal cells, the contractile ring is located inside the plasma membrane at the location of the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms beneath the plasma membrane at the mother-bud neck before mitosis. |
| | 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:0071341 | | medial cortical node | | A component of the cell division site that contains the mid1, cdr2, wee1, klp8, and blt1 proteins, and is involved in contractile ring localization. Medial cortical node complexes appear as cortical dots in the middle of the cell during interphase, and function to recruit other ring components in early mitosis. |
| | 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:0005635 | | nuclear envelope | | The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space). |
| | 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. |
