2963012-6	1988	Binding via the cell surface PG was to the COOH-terminal heparin binding domain of fibronectin.	Heparin	57-64	fibronectin 1	Mus musculus	83-94	
2963012-9	1988	These results indicate that the mammary epithelial cells have at least two distinct cell surface receptors for fibronectin: a trypsin-resistant molecule that binds cells to the sequence RGD and a trypsin-labile, heparan sulfate-rich PG that binds cells to the COOH-terminal heparin binding domain.	Heparin	274-281	fibronectin 1	Mus musculus	111-122
