Disassembly of actin filaments by the removal of actin monomers from a filament.

parallel actin filament bundle formation

Assembly of actin filament bundles in which the filaments are tightly packed (approximately 10-20 nm apart) and oriented with the same polarity.

Movement of organelles or other particles along actin filaments, or sliding of actin filaments past each other, mediated by motor proteins.

The formation of a covalent cross-link between or within protein chains.

cell projection organization and biogenesis

cell surface structure organization and biogenesis

The assembly and arrangement of a prolongation or process extending from a cell, e.g. a flagellum or axon.

Formation of a prolongation or process extending from a cell, e.g. a flagellum or axon.

Formation of a lamellipodium, a thin sheetlike extension of the surface of a migrating cell.

Formation of a microvillus, a thin cylindrical membrane-covered projection on the surface of a cell.

A filament composed of acidic and basic keratins (types I and II), typically expressed in epithelial cells. The keratins are the most diverse classes of IF proteins, with a large number of keratin isoforms being expressed. Each type of epithelium always expresses a characteristic combination of type I and type II keratins.

Formation of a microspike, a thin, stiff projection extended from the surface of a migrating cell.

actin cytoskeleton organization and biogenesis

actin cytoskeleton organisation and biogenesis

The assembly and arrangement of cytoskeletal structures comprising actin filaments and their associated proteins.

A type of intermediate filament, typically made up of one or more of the proteins vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Unlike the keratins, the type III proteins can form both homo- and heteropolymeric IF filaments.

The rapid expansion of a neuroblast population by cell division. Neuroblasts are embryonic cells which develop into nerve cells or neurons. As in, but not restricted to, the vertebrates (Vertebrata, ncbi_taxonomy_id:7742).
