EOG8DBWV6 GO:0005576 6/108 extracellular region cellular_component "The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite." [GOC:go_curators] EOG8DBWV6 GO:0040007 2/108 growth biological_process "The increase in size or mass of an entire organism, a part of an organism or a cell." [GOC:bf, GOC:ma] EOG8DBWV6 GO:0005200 1/108 structural constituent of cytoskeleton molecular_function "The action of a molecule that contributes to the structural integrity of a cytoskeletal structure." [GOC:mah] EOG8DBWV6 GO:0007010 1/108 cytoskeleton 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." [GOC:dph, GOC:jl, GOC:mah] EOG8DBWV6 GO:0005884 1/108 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."

A large structural component of the complex is an actin-like 40 nm filament composed of actin-related protein, to which other components attach." [ISBN:0198506732]
