ICAM-1 is a cell adhesion molecule that belongs to the Ig-superfamily, with a glycoprotein structure playing a key role in leukocyte recruitment into inflammatory sites, as well as in leukocyte activation and effector function.
Proteolytic cleavage of ICAM-1 results in the formation of a soluble form, sICAM-1, which is present in low-serum levels in healthy individuals but becomes elevated in inflammatory and malignant conditions.
The ICAM1 gene is located on chromosome 19 and contains two well-known single-nucleotide polymorphisms (SNP) of +241G/A (G241R) and +469A/G (K469E).
