The human ICAM2 gene maps to 17q23-25.
The intercellular adhesion molecules ICAM1 and ICAM2 are the cell-surface ligands for the lymphocyte function-associated antigen LFA-1 (CD11a/CD18) and are thought to mediate cell-cell adhesion interactions required by the immune system. However, differences in tissue distribution, inducibility of expression, and overall structure of the two ICAMs may point to their having distinct functional roles. We have used a panel of somatic cell hybrids and chromosome-mediated gene transfectants to establish the chromosomal location of the gene for ICAM2. Hybridization of an ICAM2 cDNA clone to Southern blots from this panel indicates that the human ICAM2 gene maps to chromosome 17 region q23-25.
