A Binding Interface on the I Domain of Lymphocyte Function-associated Antigen-1 (LFA-1) Required for Specific Interaction with Intercellular Adhesion Molecule 1 (ICAM-1)

Abstract excerpt

Previous studies have shown that lymphocyte function-associated antigen-1 (LFA-1) molecules containing the human alpha (CD11a) and human beta (CD18) subunits but not the murine alpha and human beta subunits can bind to human intercellular adhesion molecule 1 (ICAM-1). Using human/mouse LFA-1 alpha subunit chimeras, we mapped regions required for binding to ICAM-1 N-terminal to amino acid (aa) residue 350. Ligand...
