Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B
Carcinoembryonic Antigen-related Cell Adhesion Molecule 3, (CEACAM3) also known as CD66d and CGM1, is a 35kD transmembrane glycoprotein in the CEACAM family of the immunoglobulin superfamily. The extracellular region consists of one Ig-like V-type domain, and the cytoplasmic tail contains one ITAM. CEACAM3 is upregulated on activated neutrophils and mediates their adhesion to vascular endothelial cells. CEACAM3 binds the Opa opacity proteins on some Gram negative bacteria, leading to bacterial uptake and neutrophil death. Alternate splicing generates an isoform with a substituted cytoplasmic tail and a potentially secreted isoform that contains a highly charged and Ser/Thr-rich sequence in place of the transmembrane and cytoplasmic regions. Orthologs of human CEACAM3 have not been identified in other species.
