molecular function |
| GO:0017124 | | SH3 domain binding | | Interacting selectively and non-covalently with a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins. |
| GO:0003779 | | actin binding | | Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments. |
| 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:0030048 | | actin filament-based movement | | Movement of organelles or other particles along actin filaments, or sliding of actin filaments past each other, mediated by motor proteins. |
| 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:0008154 | | actin polymerization or depolymerization | | Assembly or disassembly of actin filaments by the addition or removal of actin monomers from a filament. |
| GO:0007411 | | axon guidance | | The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues. |
| 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:0010633 | | negative regulation of epithelial cell migration | | Any process that stops, prevents, or reduces the frequency, rate or extent of epithelial cell migration. |
| GO:1900028 | | negative regulation of ruffle assembly | | Any process that stops, prevents or reduces the frequency, rate or extent of ruffle assembly. |
| GO:0030168 | | platelet activation | | A series of progressive, overlapping events triggered by exposure of the platelets to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable hemostatic plug. |
| GO:0030838 | | positive regulation of actin filament polymerization | | Any process that activates or increases the frequency, rate or extent of actin polymerization. |
| GO:0051496 | | positive regulation of stress fiber assembly | | Any process that activates or increases the frequency, rate or extent of the assembly of a stress fiber, a bundle of microfilaments and other proteins found in fibroblasts. |
| GO:0051289 | | protein homotetramerization | | The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits. |
cellular component |
| GO:0042995 | | cell projection | | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| 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:0005925 | | focal adhesion | | Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments. |
| GO:0030027 | | lamellipodium | | A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
