Function: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 SGEF and RHOG activation. In case of rhinovirus infection acts as a cellular receptor for the virus. ,online information:ICAM-1 ,online information:Icosahedral capsid structure ,online information:Intercellular adhesion molecule entry ,polymorphism:Homozygotes with ICAM1-Kalifi Met-56 seem to have an increased risk for cerebral malaria. ,PTM:Monoubiquitinated , which is promoted by MARCH9 and leads to endocytosis. ,similarity:Belongs to the immunoglobulin superfamily. ICAM family. ,similarity:Contains 5 Ig-like C2-type (immunoglobulin-like) domains. ,subunit:Homodimer (Probable) . Interacts with human herpesvirus 8 MIR2 protein (Probable) . Interacts with MUC1 and promotes cell aggregation in epithelial cells. Interacts with SGEF. Binds to coxsackievirus A21 capsid proteins and acts as a receptor for this virus. ,
