Abstract
A large fraction of soluble protein within the interior of living cells may reversibly associate with structural elements, including proteinaceous fibers and phospholipid membranes. In this opinion, we present theoretical and experimental evidence that many of these associations are due to nonspecific attraction between the protein and the surface of the fiber or membrane, and that such associations may lead to substantial changes in the association state of the adsorbed proteins, the biological function of the adsorbed proteins, and the distribution of these proteins between the many microenvironments existing within the cell.
