摘要

Protein conformations other than those representing their unique three dimensional native states are generally believed to be insignificant structural entities occurring only during their turn over. However, the conventional compact native conformation ('C' state) of fibronectin has been found to be functionally inactive/less active as compared to its non-compact, extended ('E' state) structure formed during expression of its functions. It has been proposed that an equilibrium, 'C <-> E', between the two states is vital in explaining all the functional properties of fibronectin. The equilibrium is shifted towards right when fibronectin ought to express its activities and a 'go-slow' tag is imposed by shifting the equilibrium towards left should a need arise to that effect.
