Arf levels are tightly regulated in cells and correlate with the level of ribosome biogenesis and proliferative status of cells. Through multivalent interactions with NPM1 - a regulator of ribosome biogenesis, and Mdm2 - a regulator of cellular fate, Arf integrates within the nucleolar matrix, altering its structure, dynamics and function and therefore modulates the cell cycle.
