The present invention identified a high affinity binding sequence in collagen type III for the collagen-binding integrin I domains. Provided herein are the methods used to characterize the sequence, the peptides comprising this novel sequence and the use of the peptides in enabling cell adhesion. Also provided herein are methods to identify specific integrin inhibitors, sequences of these inhibitors and their use in inhibiting pathophysiological conditions that may arise due to integrin-collagen interaction.

Specific binding sites in collagen for integrins and use thereof

Disclosed are antibodies that block the binding of fibronectin protein to fibronectin. Also disclosed are site specifically-mutated and truncated peptide epitopes derived from the fnbA and fnbB genes of, the fnbA and fnbB genes of, and the sfb gene of, and nucleic acid segments encoding these peptides and epitopes. The anti-(fibronectin binding site) antibodies, peptides and epitopes that give rise to antibodies that block the binding of fibronectin binding proteins to fibronectin, and DNA segments encoding these proteins and are of use in various screening, diagnostic and therapeutic applications including active and passive immunization and methods for the prevention of streptococcal and staphylococcal colonization in animals or humans. These. DNA segments and the peptides derived therefrom are proposed to be of use directly in the preparation of vaccines and also for use as carrier proteins in vaccine formulations.

Provided herein is a method for inducing formation of a conformationally distinct superfibronectin by contacting plasma fibronectin with BBK32 protein or a BBK32 peptide and the BBK32-induced superfibronectin so formed. Also provided are methods of inhibiting endothelial cell proliferation, of treating pathophysiological conditions associated with endothelial cell proliferation and of inhibiting angiogenesis therein using the BBK32 protein, BBK32 peptide or the BBK32-induced superfibronectin.

Formation of superfibronectin by BBK32 and uses therefor

The present invention provides recombinant triple helical proteins or collagen-like proteins comprising a prokaryotic protein or one or more domains of a prokaryotic protein comprising a collagen-like peptide sequence of repeated Gly-Xaa-Yaa triplets and, optionally, one or more domains from a mammalian collagen. Also provided are expression vectors and host cells containing the expression vectors to produce these recombinant proteins and methods of producing the same. Additionally, antibodies are provided that are directed against a recombinant collagen-like protein that, preferably, binds an integrin. Furthermore, a method of screening for potential therapeutic compounds that inhibit the integrin-binding or integrin-interacting activities of recombinant collagen-like proteins.

Fibronectin binding protein compositions and methods of use

The present invention provides compositions and methods of inhibiting fibrin(ogen) clot formation by utilizing decorin proteoglycan as an anticoagulating and antithrombotic agent. The decorin proteoglycan comprises a decorin core protein or a fragment thereof covalently linked to a galactosaminoglycan polysaccharide. The decorin core protein acts as an anticoagulant and as a carrier for the delivery of an antithrombotic galactosaminoglycan to fibrinogen. Fibrin clotting is inhibited by the decorin proteoglycan in a concentration-dependent fashion.
