GO:0003779 | actin binding | molecular_function | Binding to monomeric or multimeric forms of actin, including actin filaments. [GOC:clt] |
GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
GO:0051694 | pointed-end actin filament capping | biological_process | The binding of a protein or protein complex to the pointed (or minus) end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits. [ISBN:071673706X] |
GO:0005865 | striated muscle thin filament | cellular_component | Filaments formed of actin and associated proteins; attached to Z discs at either end of sarcomeres in myofibrils. [ISBN:0815316194] |
GO:0030239 | myofibril assembly | biological_process | Formation of myofibrils, the repeating units of striated muscle. [GOC:mah] |
GO:0006936 | muscle contraction | biological_process | A process in which force is generated within muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. [GOC:ef, GOC:mtg_muscle, ISBN:0198506732] |
GO:0007015 | 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] |
GO:0030016 | myofibril | cellular_component | The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism. [ISBN:0815316194] |
GO:0005856 | cytoskeleton | cellular_component | A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes 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, PMID:16959967, PMID:27419875] |
GO:0005523 | tropomyosin binding | molecular_function | Binding to tropomyosin, a protein associated with actin filaments both in cytoplasm and, in association with troponin, in the thin filament of striated muscle. [GOC:curators, ISBN:0815316194] |
