Abstract

Intercellular adhesion molecule-4 binds alpha(4)beta(1) and alpha(V)-family integrins through novel integrin-binding mechanisms.

Blood, 2001; PubMed, Homo sapiens ICAM4 — Homo sapiens ITGB1

ABSTRACT: The LW blood group glycoprotein, ICAM-4, is a member of the intercellular adhesion molecule (ICAM) family expressed in erythroid cells. To begin to address the function of this molecule, ligands for ICAM-4 on hemopoietic and nonhemopoietic cell lines were identified. Peptide inhibition studies suggest that adhesion of cell lines to an ICAM-4-Fc construct is mediated by an LDV-inhibitable integrin on hemopoietic cells and an RGD-inhibitable integrin on nonhemopoietic cells. Antibody inhibition studies identified the hemopoietic integrin as alpha(4)beta(1.) Antibody inhibition studies on alpha(4)beta(1)-negative, nonhemopoietic cell lines suggested that adhesion of these cells is mediated by alpha(V) integrins (notably alpha(V)beta(1) and alpha(V)beta(5)). The structure of ICAM-4 modeled on the crystal structure of ICAM-2 was used to identify surface-exposed amino acid residues for site-directed mutagenesis. Neither an unusual LETS nor an LDV motif in the first domain of ICAM-4 was critical for integrin binding. ICAM-4 is the first ICAM family member shown to be a ligand for integrins other than those of the beta(2) family, and the data suggest that ICAM-4 has a novel integrin-binding site(s). These findings suggest a role for ICAM-4 in normal erythropoiesis and may also be relevant to the adhesive interactions of sickle cells.
