ICAM1: a type I membrane protein of the immunoglobulin superfamily. Is a ligand for the leukocyte adhesion LFA-1 protein (Integrin alpha-L/beta-2) and a Rhinovirus receptor. Typically expressed on endothelial cells and cells of the immune system. ICAM1 binds to integrins of type CD11a / CD18, or CD11b / CD18. Its expression is activated by p53 in an NF-kappaB-independent manner. Induced by TNFalpha in a process that involves IKKbeta.
