This antimicrobial gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene may play a role in normal lymphocyte recirculation and homing. It also plays an important role in trafficking of T cells in thymus, and in T cell and B cell migration to secondary lymphoid organs. It specifically binds to chemokine receptor CCR7.,CCL19,CKb11,ELC,MIP-3b,MIP3B,SCYA19,Immunology & Inflammation,Cytokines,Cell Intrinsic Innate Immunity Signaling Pathway,Chemokines,Chemokine,CCL19
