======= ICAM4 ======= == Gene Information == * **Official Symbol**: ICAM4 * **Official Name**: intercellular adhesion molecule 4 (Landsteiner-Wiener blood group) * **Aliases and Previous Symbols**: N/A * **Entrez ID**: [[https://www.ncbi.nlm.nih.gov/gene/?term=3386|3386]] * **UniProt**: [[https://www.uniprot.org/uniprot/Q14773|Q14773]] * **Interactions**: [[https://thebiogrid.org/search.php?search=ICAM4&organism=9606|BioGRID]] * **PubMed articles**: [[https://www.ncbi.nlm.nih.gov/pubmed/?term=gene%20ICAM4|Open PubMed]] * **OMIM**: [[https://omim.org/entry/614088|Open OMIM]] == Function Summary == * **Entrez Summary**: This gene encodes the Landsteiner-Wiener (LW) blood group antigen(s) that belongs to the immunoglobulin (Ig) superfamily, and that shares similarity with the intercellular adhesion molecule (ICAM) protein family. This ICAM protein contains 2 Ig-like C2-type domains and binds to the leukocyte adhesion LFA-1 protein. The molecular basis of the LW(A)/LW(B) blood group antigens is a single aa variation at position 100; Gln-100=LW(A) and Arg-100=LW(B). Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2). ICAM4 is also a ligand for alpha-4/beta-1 and alpha-V integrins. {ECO:0000269|PubMed:11435317}. |ICAM N| |integrin binding| |extracellular matrix organization| |extracellular structure organization| |cell-cell adhesion| |cell adhesion| |biological adhesion| |regulation of immune response| |integral component of plasma membrane| |regulation of immune system process| |extracellular region| \\ === CRISPR Data === No hits were found.
