intercellular adhesion molecule 1 (CD54), human rhinovirus receptor
Major group rhinovirus receptor
Surface antigen of activated B cells, BB2
機能ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2). During leukocyte trans-endothelial migration, ICAM1 engagement promotes the assembly of endothelial apical cups through ARHGEF26/SGEF and RHOG activation. In case of rhinovirus infection acts as a cellular receptor for the virus.
