Identification and Characterization of a Heparin Binding Site within the NC I Domain of Chicken Collagen XlV
نویسنده
چکیده
Collagen XIV is known to bind to the dermatan sulfate chain of decorin and to the heparan sulfate chain of perlecan. To study its possible interaction with glycosaminoglycans, the NC1 domain of chicken collagen XIV was overproduced in E. coll. Purified NCI* (6-119)* appears poorly organized (the asterisks indicate the presence of extension sequences), but V8-protease generated fragments containing the 84-108 basic sequence tend to fold into (x-helix. These fragments interact specifically with heparin, which induces an s-helical fold with a maximum effect for equimolar heparin/peptide ratio. These data demonstrate the existence of a glycosaminoglycan binding site in NC1.

The glycosaminoglycan chains of cell surface heparan sulfate proteoglycans are believed to regulate cell adhesion, proliferation, and extracellular matrix assembly, through their interactions with heparin-binding proteins (for review see Ruoslahti, E. 1988. Annu. Rev. Cell Biol. 4:229-255; and Bernfield, M., R. Kokenyesi, M. Kato, M. T. Hinkes, J. Spring, R. L. Gallo, and E. J. Lose. 1992. Annu...

Fibronectin (FN) is one of the essential component of the extra cellular matrix and their important role is as regulator of cellular activities and also fibronectin is an important scaffold for maintaining tissue. Fibronectin conformational changes expose additional binding sites that participate in fibril formation and in conversion of fibrils into a stabilized, insoluble form. In fact fibrone...
متن کاملThe binding of heparin to type IV collagen: domain specificity with identification of peptide sequences from the alpha 1(IV) and alpha 2(IV) which preferentially bind heparin.
Three distinctive heparin-binding sites were observed in type IV collagen by the use of rotary shadowing: in the NC1 domain and at distances 100 and 300 nm from the NC1 domain. Scatchard analysis indicated different affinities for these sites. Electron microscopic analysis of heparin-type IV collagen interaction with increasing salt concentrations showed the different affinities to be NC1 great...
متن کاملStructural analysis of the heparin-binding site of the NC1 domain of collagen XIV by CD and NMR.
Type XIV collagen, a fibril-associated collagen with interrupted triple helices (FACIT), interacts with the surrounding extracellular matrix and/or with cells via its binding to glycosaminoglycans (GAGs). To further characterize such interactions in the NC1 domain of chicken collagen XIV, we identified amino acids essential for heparin binding by affinity chromatography analysis after proteolyt...

We have previously identified three distinctive amino acid sequences from type IV collagen which specifically bound to heparin and also inhibited the binding of heparin to intact type IV collagen. One of these chemically synthesized domains, peptide Hep-I, has the sequence TAGSCLRKFSTM and originates from the a1(noncollagenous [NC1]) chain of type IV collagen (Koliakos, G. G., K. K. Koliakos, L...
