Endothelial Cell Adhesion Molecule (ESAM) (C-Term), (AA 30-247) protein
Description
Recombinant Human Endothelial Cell Adhesion Molecule/ESAM is produced by our mammalian expression system. The target protein is expressed with sequence (Gln30-Ala247) of Human ESAM fused with a FC tag at the C-terminus. Endothelial Cell Adhesion Molecule (ESAM) is a 55 kDa type I transmembrane glycoprotein member of the JAM family of immunoglobulin superfamily molecules. The 390 AA Human ESAM contains a 216 AA extracellular domain (ECD) with a V-type and a C2-type immunoglobulin (Ig) domain. ESAM is specifically expressed at endothelial tight junctions and on activated platelets and performs homophilic adhesion activity. The adaptor protein membrane-associated guanylate kinase MAGI-1 has been identified as an intracellular binding partner of ESAM. In addition, ESAM at endothelial tight junctions participates in the migration of neutrophils through the vessel wall, possibly by influencing endothelial cell contacts. ESAM-deficient mice were described with lowered angiogenic potential, and accordingly, overexpression of ESAM is closely associated with certain tumor growth and metastasis. ESAM is expressed on endothelial cells, activated platelets and megakaryocytes. The ECD of human and mouse ESAM share 69 % AA identity.
