Human Intercellular Adhesion Molecule 1, ICAM-1 ELI

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.

(Microbial infection) Acts as a receptor for major receptor group rhinovirus A-B capsid proteins.

(Microbial infection) Acts as a receptor for Coxsackievirus A21 capsid proteins.

(Microbial infection) Upon Kaposi's sarcoma-associated herpesvirus/HHV-8 infection, is degraded by viral E3 ubiquitin ligase MIR2, presumably to prevent lysis of infected cells by cytotoxic T-lymphocytes and NK cell.
