collagen and is the receptor for echovirus 1. Binding sites for both collagen and echovirus 1
have been mapped to the I domain within the α2 subunit of the VLA-2 α2β1 heterodimer.
Although murine VLA-2 interacts with collagen, it does not bind virus. We have used isolated
human-murine chimeric I domains expressed as glutathione S-transferase fusion proteins in
Escherichia coli to identify two groups of amino acids, 199–201 and 212–216 …
