Contact between dendritic cells (DC) and resting T cells is essential to initiate a primary immune response. CD209 binds the intracellular adhesion molecule 3 (ICAM3) with very high affinity. CD209 interacts primarily with the immunoglobulin (Ig)-like second domain of ICAM2 and ICAM3. CD209-ICAM3 interaction mediates clustering of DCs with naive T cells forming a DC-T cell synapse (Geijtenbeek et al. 2000). CD209 binding to ICAM3 is calcium dependent, and CD209 CRD (carbohydrate recognition domain) binds two Ca2+ ions, one essential for tertiary structure and the other for coordinating ligand binding (Feinberg et al. 2001, Svajger et al. 2010).
