产品介绍 : CEA-related cell adhesion molecules (CEACAM) belong to the carcinoembryonic antigen (CEA) family. It consists of seven CEACAM (CEACAM 1, CEACAM 3-CEACAM 8) and 11 pregnancy-specific glyco-protein (PSG 1-PSG 11) members. The CEA family proteins belong to the immunoglobulin (Ig) superfamily and are composed of one Ig variable-like (IgV) and a varying number (0-6) of Ig constant-like (IgC) domains. CEACAM molecules are membrane-bound either via a transmembrane domain or a glycosyl phosphatidyl inositol (GPI) anchor. CEACAM molecules are differentially expressed in epithelial cells or in leucocytes. Over-expression of CEA/ CEACAM 5 in tumors of epithelial origin is the basis of its wide-spread use as a tumor marker. The function of CEACAM family members varies widely: they function as cell adhesion molecules, tumor suppressors, regulators of lymphocyte and dendritic cell activation, receptors of Neisseria species and other bacteria.
Function:
Cell surface glycoprotein that plays a role in cell adhesion and in intracellular signaling. Receptor for E.coli Dr adhesins.
Subunit:
Homodimer. Binding of E.coli Dr adhesins leads to dissociation of the homodimer.
Subcellular Location:
Cell membrane; Lipid-anchor, GPI-anchor
Tissue Specificity:
Found in adenocarcinomas of endodermally derived digestive system epithelium and fetal colon.
Similarity:
Belongs to the immunoglobulin superfamily. CEA family.
Contains 7 Ig-like (immunoglobulin-like) domains.
SWISS:
P06731
Gene ID:
1048

CEA是一种胚胎性抗原,主要存在于胎儿消化道上皮组织,胰腺和肝癌中。CEA广泛存在各种上皮性肿瘤,尤其是胃肠道恶性肿瘤,CEA分布阳性类型与肿瘤的恶性度有关。CEA与EMA一样可作为上皮性恶性肿瘤的重要标记。
