The function of Ensembl gene identifier ENSG00000108622 (ICAM2, intercellular adhesion molecule 2) is as follows. 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 on resting cells (PubMed:10077629, PubMed:1676048, PubMed:2497351). Also endothelial blood vessels receptor ligand of dendritic cell (DC) CD209 signaling receptor that mediates triggering transendothelial migration of DC presursors from blood into peripheral tissues and, subsequently, into lymphoid tissues (PubMed:11017109). Mediates adhesive interactions important for antigen presentation, lymphocyte recirculation, and other cellular interactions important for immune response and surveillance (Probable). {ECO:0000269|PubMed:10077629, ECO:0000269|PubMed:11017109, ECO:0000269|PubMed:1676048, ECO:0000269|PubMed:2497351, ECO:0000305|PubMed:1676048}.
