Critical amino acids in the lymphocyte function-associated antigen-1 I domain mediate intercellular adhesion molecule 3 binding and immune function

Abstract

We have identified amino acid residues within the evolutionarily conserved I domain of the alpha-chain (CD11a) of the leukocyte integrin leukocyte function-associated antigen (LFA) 1 that are critical for intercellular adhesion molecule (ICAM) 3 (CD50) binding. ICAM-3, a ligand of LFA-1, is thought to mediate intercellular adhesion essential for the… (More)
