Descriptions Names[Advanced Search]

The process of creating protein polymers, compounds composed of a large number of component monomers; polymeric proteins may be made up of different or identical monomers. Polymerization occurs by the addition of extra monomers to an existing poly- or oligomeric protein. Any process that modulates the frequency, rate or extent of the assembly of actin filaments by the addition of actin monomers to a filament. Any process that activates or increases the frequency, rate or extent of actin polymerization. Assembly or disassembly of actin filaments by the addition or removal of actin monomers from a filament. Any process that stops, prevents or reduces the frequency, rate or extent of actin polymerization. Assembly of actin filaments by the addition of actin monomers to a filament. 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. Any process carried out at the cellular level by which macromolecules aggregate, disaggregate, or are modified, resulting in the formation, disassembly, or alteration of a macromolecular complex. The aggregation, arrangement and bonding together of a set of components to form a protein complex, occurring at the level of an individual cell.
