Structural comparison of fibronectins from normal and transformed cells. 1981

I U Ali, and T Hunter

Comparative study of the structures of fibronectins from normal and transformed cells by partial proteolysis as well as by tryptic peptide fingerprinting and analysis of phosphorylation show that: 1) fibronectin molecules from normal and transformed cells probably have very similar primary structures; 2) the phosphorylation of fibronectin is a highly specific and conserved phenomenon; 3) fibronectin from both normal and transformed cells is phosphorylated only on serine residues; 4) although the major sites of phosphorylation in fibronectin are the same in normal and transformed cells, fibronectin from transformed cells appears to be phosphorylated to a much higher extent than that from normal cells.

D002460	Cell Line	Established cell cultures that have the potential to propagate indefinitely.	Cell Lines,Line, Cell,Lines, Cell
D002472	Cell Transformation, Viral	An inheritable change in cells manifested by changes in cell division and growth and alterations in cell surface properties. It is induced by infection with a transforming virus.	Transformation, Viral Cell,Viral Cell Transformation,Cell Transformations, Viral,Transformations, Viral Cell,Viral Cell Transformations
D005353	Fibronectins	Glycoproteins found on the surfaces of cells, particularly in fibrillar structures. The proteins are lost or reduced when these cells undergo viral or chemical transformation. They are highly susceptible to proteolysis and are substrates for activated blood coagulation factor VIII. The forms present in plasma are called cold-insoluble globulins.
