Mankelow, Frances A. Spring, Stephen F. Parsons, R. Leo Brady, Narla Mohandas, Joel A. Chasis, and David J. Anstee From the Bristol Institute for Transfusion Sciences, Bristol, United Kingdom; Department of Biochemistry, University of Bristol, Bristol, United Kingdom; New York Blood Center, New York, NY; and University of California Lawrence Berkeley National Laboratory, Berkeley, CA. Intercellular adhesion molecule-4 (ICAM-4, syn. LW glycoprotein) interacts with the integrins L2, M2, A41, the V family, and IIb3. Systematic mutagenesis of surface-exposed residues conserved between human and murine ICAM-4 defined 12 single amino-acid changes that affect the interaction of ICAM-4 with V integrins. Mutation of 10 of these residues, 8 of which are spatially close on the surface of the molecule, led to a reduction in adhesion. Moreover, peptides corresponding to regions of ICAM-4 involved in its interaction with V integrins inhibited these interactions. The other 2 mutations increased the extent of interaction of ICAM-4 with V integrins. These mutations appear to prevent glycosylation of N160, suggesting that changes in glycosylation may modulate ICAM-4–V integrin interactions. The region of ICAM-4 identified as the binding site for V integrins is adjacent to the binding sites for L2 and M2. Selective binding of ICAM-4 to different integrins may be important for a variety of normal red cell functions and also relevant to the pathology of thrombotic disorders and vasoocclusive events in sickle cell disease. Our findings suggest the feasibility of developing selective inhibitors of ICAM-4–integrin adhesion of therapeutic value in these diseases.
