2050739-0	1991	NCAM polysialic acid can regulate both cell-cell and cell-substrate interactions.	polysialic acid	5-20	neural cell adhesion molecule 1	Homo sapiens	0-4	
2050739-1	1991	We have proposed previously that the polysialic acid (PSA) moiety of NCAM can influence membrane-membrane apposition, and thereby serve as a selective regulator of a variety of contact-dependent cell interactions.	polysialic acid	37-52	neural cell adhesion molecule 1	Homo sapiens	69-73
