| | GO:0017048 | | Rho GTPase binding | | Interacting selectively and non-covalently with Rho protein, any member of the Rho subfamily of the Ras superfamily of monomeric GTPases. Proteins in the Rho subfamily are involved in relaying signals from cell-surface receptors to the actin cytoskeleton. |

| | GO:0005522 | | profilin binding | | Interacting selectively and non-covalently with profilin, an actin-binding protein that forms a complex with G-actin and prevents it from polymerizing to form F-actin. |
| | 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: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:0045010 | | actin nucleation | | The initial step in the formation of an actin filament, in which actin monomers combine to form a new filament. Nucleation is slow relative to the subsequent addition of more monomers to extend the filament. |
| | GO:0071519 | | actomyosin contractile ring actin filament bundle assembly | | A process of actin filament bundle formation that occurs in the context of assembling an actomyosin contractile ring during cytokinesis. |
| | GO:0051016 | | barbed-end actin filament capping | | The binding of a protein or protein complex to the barbed (or plus) end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits. |
| | GO:0007118 | | budding cell apical bud growth | | Growth at the tip of a bud, in a cell that reproduces by budding. |
| | GO:0016043 | | cellular component organization | | A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component. |
| | GO:0000132 | | establishment of mitotic spindle orientation | | A cell cycle process that sets the alignment of mitotic spindle relative to other cellular structures. |
| | GO:0070649 | | formin-nucleated actin cable assembly | | The aggregation, arrangement and bonding together of a set of components to form a formin-nucleated actin cable. A formin-nucleated actin cable is an actin filament bundle that consists of short filaments organized into bundles of uniform polarity, and is nucleated by formins. |
| | GO:2000251 | | positive regulation of actin cytoskeleton reorganization | | Any process that activates or increases the frequency, rate or extent of actin cytoskeleton reorganization. |
| | GO:0032880 | | regulation of protein localization | | Any process that modulates the frequency, rate or extent of any process in which a protein is transported to, or maintained in, a specific location. |
| cellular component |
|---|
| | GO:0005884 | | actin filament | | A filamentous structure formed of a two-stranded helical polymer of the protein actin and associated proteins. Actin filaments are a major component of the contractile apparatus of skeletal muscle and the microfilaments of the cytoskeleton of eukaryotic cells. The filaments, comprising polymerized globular actin molecules, appear as flexible structures with a diameter of 5-9 nm. They are organized into a variety of linear bundles, two-dimensional networks, and three dimensional gels. In the cytoskeleton they are most highly concentrated in the cortex of the cell just beneath the plasma membrane. |
| | GO:0042995 | | cell projection | | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| | GO:0005935 | | cellular bud neck | | The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding. |
| | GO:0005934 | | cellular bud tip | | The end of a cellular bud distal to the site of attachment to the mother cell. |
| | 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:0000131 | | incipient cellular bud site | | The portion of the budding yeast plasma membrane where a daughter cell will emerge. The yeast marks this spot with bud-site selection proteins before bud emergence occurs. Actin is polarized to this spot just prior to and during bud emergence. |
| | GO:0043332 | | mating projection tip | | The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| | GO:0000133 | | polarisome | | Protein complex that plays a role in determining cell polarity by directing the localized assembly of actin filaments at polarization sites; in Saccharomyces the polarisome includes Bni1p, Spa2p, Pea2p, and Bud6p. |
| | GO:0032587 | | ruffle membrane | | The portion of the plasma membrane surrounding a ruffle. |
