Specific binding sites in collagen for integrins and use thereof
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.
1. An expression vector comprising:
a DNA sequence encoding a recombinant collagen or collagen-like protein of SEQ ID NO: 15 wherein the amino acid Xaa is hydroxyproline.
2. A host cell comprising and expressing the expression vector of claim 1 .
