Fragments of intercellular adhesion molecule 1 (ICAM- 1)
containing only the two most N terminal of its five immunoglobulin SF
domains bind to rhinovirus 3 with the same affinity and kinetics as a
fragment with the entire extracellular domain. The fully active
two-domain fragments contain 5 or 14 more residues than a previously
described fragment that is only partially active. Comparison of X-ray
crystal structures show differences at the bottom of domain 2. Four
different glycoforms of ICAM- 1 bind with identical kinetics.
