| molecular function |
|---|
| | GO:0003779 | | actin binding | | Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments. |
| | GO:0051015 | | actin filament binding | | Interacting selectively and non-covalently with an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits. |
| | GO:0005509 | | calcium ion binding | | Interacting selectively and non-covalently with calcium ions (Ca2+). |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0030674 | | protein binding, bridging | | The binding activity of a molecule that brings together two or more protein molecules, or a protein and another macromolecule or complex, through a selective, non-covalent, often stoichiometric interaction, permitting those molecules to function in a coordinated way. |
| biological process |
|---|
| | GO:0051666 | | actin cortical patch localization | | Any process in which actin cortical patches are transported to, or maintained in, a specific location. An actin cortical patch is a discrete actin-containing structure found just beneath the plasma membrane in fungal cells. |
| | GO:0051764 | | actin crosslink formation | | The process in which two or more actin filaments are connected together by proteins that act as crosslinks between the filaments. The crosslinked filaments may be on the same or differing axes. |
| | GO:0030036 | | actin cytoskeleton organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins. |
| | GO:0051017 | | actin filament bundle assembly | | The assembly of actin filament bundles; actin filaments are on the same axis but may be oriented with the same or opposite polarities and may be packed with different levels of tightness. |
| | GO:0030437 | | ascospore formation | | The process in which cells that are products of meiosis acquire the specialized features of ascospores. Ascospores are generally found in clusters of four or eight spores within a single mother cell, the ascus, and are characteristic of the ascomycete fungi (phylum Ascomycota). |
| | GO:0006897 | | endocytosis | | A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle. |
| | GO:0071963 | | establishment or maintenance of cell polarity regulating cell shape | | Any cellular process that results in the specification, formation or maintenance of a polarized intracellular organization or cell growth patterns that regulate the shape of a cell. |
| | GO:1903475 | | mitotic actomyosin contractile ring assembly | | Any actomyosin contractile ring assembly that is involved in mitotic cytokinesis. |
| | 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:0030835 | | negative regulation of actin filament depolymerization | | Any process that stops, prevents, or reduces the frequency, rate or extent of actin depolymerization. |
| | GO:0008360 | | regulation of cell shape | | Any process that modulates the surface configuration of a cell. |
| cellular component |
|---|
| | GO:0030479 | | actin cortical patch | | An endocytic patch that consists of an actin-containing structure found at the plasma membrane in cells; formed of networks of branched actin filaments that lie just beneath the plasma membrane and assemble, move, and disassemble rapidly. An example of this is the actin cortical patch found in Saccharomyces cerevisiae. |
| | GO:0032432 | | actin filament bundle | | An assembly of actin filaments that are on the same axis but may be oriented with the same or opposite polarities and may be packed with different levels of tightness. |
| | 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. |
