CEACAM20 (Carcinoembryonic Antigen Related Cell Adhesion Molecule 20) is a Protein Coding gene. An important paralog of this gene is CEACAM5. Together with the tyrosine-protein kinase SYK, enhances production of the cytokine CXCL8/IL-8 via the NFKB pathway and may thus have a role in the intestinal immune response.
