biological process |
| GO:0051693 | | actin filament capping | | The binding of a protein or protein complex to the end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits. |
| GO:0030042 | | actin filament depolymerization | | Disassembly of actin filaments by the removal of actin monomers from a filament. |
| GO:0030041 | | actin filament polymerization | | Assembly of actin filaments by the addition of actin monomers to a filament. |
| GO:0051014 | | actin filament severing | | The process in which an actin filament is broken down into smaller filaments. |
| 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:0006915 | | apoptotic process | | A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died. |
| GO:0071364 | | cellular response to epidermal growth factor stimulus | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an epidermal growth factor stimulus. |
| GO:0035729 | | cellular response to hepatocyte growth factor stimulus | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a hepatocyte growth factor stimulus. |
| GO:0060327 | | cytoplasmic actin-based contraction involved in cell motility | | The actin filament-based movement by which cytoplasmic actin filaments slide past one another resulting in a contraction that propels the cell from one place to another. |
| GO:0007010 | | 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. |
| GO:0007173 | | epidermal growth factor receptor signaling pathway | | A series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription. |
| GO:0043154 | | negative regulation of cysteine-type endopeptidase activity involved in apoptotic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process. |
| GO:0032233 | | positive regulation of actin filament bundle assembly | | Any process that activates or increases the frequency, rate or extent of the assembly of actin filament bundles. |
| GO:0030335 | | positive regulation of cell migration | | Any process that activates or increases the frequency, rate or extent of cell migration. |
| GO:0010634 | | positive regulation of epithelial cell migration | | Any process that activates or increases the frequency, rate or extent of epithelial cell migration. |
| GO:0051125 | | regulation of actin nucleation | | Any process that modulates the frequency, rate or extent of actin nucleation, the initial step in the formation of an actin filament in which actin monomers combine to form a new filament. |
| GO:0008360 | | regulation of cell shape | | Any process that modulates the surface configuration of a cell. |
| GO:2000392 | | regulation of lamellipodium morphogenesis | | Any process that modulates the frequency, rate or extent of lamellipodium morphogenesis. |

| GO:0009617 | | response to bacterium | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a bacterium. |
cellular component |
| 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: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:0030175 | | filopodium | | Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft. |

| GO:0001726 | | ruffle | | Projection at the leading edge of a crawling cell; the protrusions are supported by a microfilament meshwork. |
