Anti-CEA
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.
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.
Subunit : Homodimer.

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。
