2514791-3	1989	In an effort to elucidate the factors controlling the expression of N-linked oligosaccharides on this polypeptide, we have used a combination of sequential exoglycosidase digestion, methylation analysis, and controlled acetolysis to determine the oligosaccharide structures at each of the N-glycosylation sites of type I and type II t-PA when isolated from a human colon fibroblast cell strain and from a Bowes melanoma cell line.	n-linked oligosaccharides	68-93	plasminogen activator, tissue type	Homo sapiens	333-337	
3937276-5	1985	The possible role of N-linked oligosaccharides for the biological activity of t-PA was studied using t-PA secreted by melanoma cells in the presence of tunicamycin, an inhibitor of N-glycosylation.	n-linked oligosaccharides	21-46	plasminogen activator, tissue type	Homo sapiens	78-82
