Immunogens

Immunogen:

Purified recombinant fragment of human CEA expressed in E. Coli.

Uniprot:

P06731(CEAM5_HUMAN) >>Visit HPA database.

Gene(ID):
CEACAM5(1048)
Expression:
P06731 CEAM5_HUMAN:

Expressed in columnar epithelial and goblet cells of the colon (at protein level) (PubMed:10436421). Found in adenocarcinomas of endodermally derived digestive system epithelium and fetal colon.

Description:
Carcino Embryonic Antigen (CEA) is synthesised during development in the fetal gut, and is re-expressed in increased amounts in intestinal carcinomas and several other tumors. Antibodies to CEA are useful in identifying the origin of various metastatic adenocarcinomas and in distinguishing pulmonary adenocarcinomas (60 to 70% are CEA+) from pleural mesotheliomas (rarely or weakly CEA+).

Research Backgrounds

Function:

Cell surface glycoprotein that plays a role in cell adhesion, intracellular signaling and tumor progression. Mediates homophilic and heterophilic cell adhesion with other carcinoembryonic antigen-related cell adhesion molecules, such as CEACAM6. Plays a role as an oncogene by promoting tumor progression; induces resistance to anoikis of colorectal carcinoma cells.

(Microbial infection) Receptor for E.coli Dr adhesins. Binding of E.coli Dr adhesins leads to dissociation of the homodimer.

PTMs:

Complex immunoreactive glycoprotein with a MW of 180 kDa comprising 60% carbohydrate.

Subcellular Location:

Cell membrane>Lipid-anchor. Apical cell membrane. Cell surface.
Note: Localized to the apical glycocalyx surface.
