Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Cell adhesion molecule that functions as a receptor ligand of the signaling receptor ITGAL:ITGB2/LFA-1 (lymphocyte-function associated (LFA) molecule 1) ensuring leukocyte cell-cell adhesion, by providing a calibrated system to namely adjust T-cell killing to the antigen stimulation strength (PubMed:3086451, PubMed:3340213, PubMed:38195629). Also functions as a ligand receptor of the signaling receptor ITGAM:ITGB2/MAC-1 ensuring adhesion between stimulated neutrophils and stimulated endothelial cells (PubMed:1980124). During leukocyte trans-endothelial migration, ICAM1 engagement promotes the assembly of endothelial apical cups through ARHGEF26/SGEF and RHOG activation (PubMed:17875742). Promotes cell aggregation in epithelial cells through interaction with MUC1 (PubMed:11173916).FUNCTION (Microbial infection) Acts as a receptor for major receptor group rhinovirus A-B capsid proteins.FUNCTION (Microbial infection) Acts as a receptor for Coxsackievirus A21 capsid proteins.FUNCTION (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.SUBUNIT Homodimer (PubMed:12526797, PubMed:15099525). Interacts with MUC1 and promotes cell aggregation in epithelial cells (PubMed:11173916). Interacts with ARHGEF26/SGEF (PubMed:17875742). Interacts (on T cell side) with CD81, CD247 and CD9 at immunological synapses between antigen-presenting cells and T cells (PubMed:23858057).SUBUNIT (Microbial infection) Interacts with major receptor group rhinovirus A-B capsid proteins (PubMed:1968231, PubMed:2538243).SUBUNIT (Microbial infection) Interacts with Coxsackievirus A21 capsid proteins (PubMed:11160747, PubMed:16004874, PubMed:9539703).INTERACTION Expressed on non-hematopoietic cells such as vascular endothelial cells, thymic epithelial cells, certain other epithelial cells, and fibroblasts, and on hematopoietic cells such as tissue macrophages, mitogen-stimulated T lymphocyte blasts, and germinal center dendritic cells in tonsils, lymph nodes, and Peyer's patches (PubMed:3086451). Expressed in low amounts on peripheral blood leukocytes (PubMed:3086451).INDUCTION Up-regulated by coagulation factor Xa (F10) in atrial tissues (PubMed:24041930). Up-regulated in atrial tissues by rapid pacing resembling atrial fibrillation (PubMed:24041930). Induced by either inflammatory cytokines (PubMed:3086451, PubMed:3340213).PTM Monoubiquitinated, which is promoted by MARCH9 and leads to endocytosis.POLYMORPHISM Variant p.Lys56Met, known as ICAM1-Kilifi, may influence susceptibility to cerebral malaria [MIM:611162].SIMILARITY Belongs to the immunoglobulin superfamily.
