== Function ==
 +
[https://www.uniprot.org/uniprot/ICAM1_HUMAN ICAM1_HUMAN] 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.<ref>PMID:2538243</ref> <ref>PMID:1968231</ref> <ref>PMID:11173916</ref> <ref>PMID:17875742</ref>

We have determined the 3.0 A crystal structure of the three C-terminal domains 3-5 (D3-D5) of ICAM-1. Combined with the previously known N-terminal two-domain structure (D1D2), a model of an entire ICAM-1 extracellular fragment has been constructed. This model should represent a general architecture of other ICAM family members, particularly ICAM-3 and ICAM-5. The observed intimate dimerization interaction at D4 and a stiff D4-D5 stem-like architecture provide a good structural explanation for the existence of preformed ICAM-1 cis dimers on the cell membrane. Together with another dimerization interface at D1, a band-like one-dimensional linear cluster of ICAM-1 on an antigen-presenting cell (APC) surface can be envisioned, which might explain the formation of an immunological synapse between an activated T cell and APC which is critical for T cell receptor signaling.
