[ISBN:0198547684] EOG8HMMQQ GO:0005524 5/103 ATP binding molecular_function "Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator." [ISBN:0198506732] EOG8HMMQQ GO:0005856 4/103 cytoskeleton cellular_component "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." [GOC:mah, ISBN:0198547684, PMID:16959967] EOG8HMMQQ GO:0005200 1/103 structural constituent of cytoskeleton molecular_function "The action of a molecule that contributes to the structural integrity of a cytoskeletal structure." [GOC:mah] EOG8HMMQQ GO:0005884 1/103 actin filament cellular_component "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."

[GOC:dph, GOC:jl, GOC:mah] EOG8HMMQQ GO:0051489 1/103 regulation of filopodium assembly biological_process "Any process that modulates the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone." [GOC:ai, GOC:dph, GOC:tb] EOG8HMMQQ GO:0007015 1/103 actin filament organization biological_process "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. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking." [GOC:mah] EOG8HMMQQ GO:0005885 1/103 Arp2/3 protein complex cellular_component "A stable protein complex that contains two actin-related proteins, Arp2 and Arp3, and five novel proteins (ARPC1-5), and functions in the nucleation of branched actin filaments."
