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:0003785 | | actin monomer binding | | Interacting selectively and non-covalently with monomeric actin, also known as G-actin. |
| GO:0005504 | | fatty acid binding | | Interacting selectively and non-covalently with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis. |
| GO:0008289 | | lipid binding | | Interacting selectively and non-covalently with a lipid. |
| 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:0030041 | | actin filament polymerization | | Assembly of actin filaments by the addition of actin monomers to a filament. |
| GO:0044351 | | macropinocytosis | | An endocytosis process that results in the uptake of liquid material by cells from their external environment by the 'ruffling' of the cell membrane to form heterogeneously sized intracellular vesicles called macropinosomes, which can be up to 5 micrometers in size. |
cellular component |
| GO:0015629 | | actin cytoskeleton | | The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0045335 | | phagocytic vesicle | | A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis. |
| 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. |
