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.

age-dependent response to reactive oxygen species

Responses that arise in conjunction with increasing age and are induced by any reactive oxygen species, including singlet oxygen, superoxide, and oxygen free radicals.

Catalysis of the reaction: 5-alpha-cholest-7-en-3-beta-ol + O2 = cholesta-5,7-dien-3-beta-ol + H2O2.

Sodium:potassium-exchanging ATPases are tetrameric proteins, consisting of two large alpha subunits and two smaller beta subunits. The alpha subunits bear the active site and penetrate the membrane, while the beta subunits carry oligosaccharide groups and face the cell exterior.

Catalysis of the reaction: biotin amide + H2O = biotin + NH3.

A complex that binds interleukin-13; consists of two chains, interleukin-4 receptor alpha chain and interleukin-4 receptor alpha chain.

Catalysis of the reaction: L-pipecolate + O2 = 2,3,4,5-tetrahydropyridine-2-carboxylate + H2O2.

Catalysis of the reaction: xylitol + NADP+ = L-xylulose + NADPH.

Processes of T cell selection that occur in the thymus.

The directed movement of metal ions, any metal ion with an electric charge, into, out of, within or between cells.
