Function
Cell surface glycoprotein that plays a role in cell adhesion, intracellular signaling and tumor progression (PubMed:10864933, PubMed:10910050, PubMed:2803308). Mediates homophilic and heterophilic cell adhesion with other carcinoembryonic antigen-related cell adhesion molecules, such as CEACAM6 (PubMed:2803308). Plays a role as an oncogene by promoting tumor progression; induces resistance to anoikis of colorectal carcinoma cells (PubMed:10910050). (Microbial infection) Receptor for E.coli Dr adhesins. Binding of E.coli Dr adhesins leads to dissociation of the homodimer.

Notes
While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.
Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.
The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Support team to know which antibody pair is suitable for this protein.

- Activity summary
CEACAM5 also known as Carcinoembryonic Antigen (CEA) or CD66e is a glycoprotein found mainly on the surface of epithelial cells. This protein has a mass of approximately 180 kDa. It gets expressed in a variety of tissues with high expression in the gastrointestinal tract including the colon and rectum. CEACAM5 is a member of the immunoglobulin superfamily and plays a role in cell adhesion influencing how cells stick to each other.
- Biological function summary
CEACAM5 contributes to cellular processes involving cell adhesion and immune response modulation. This protein operates as part of a larger group of cell adhesion molecules and does not function as part of a complex. CEACAM5 can affect the interactions between cells and the extracellular matrix which has implications for tissue structuring and integrity. It helps the immune system recognize and respond to infectious agents or cellular anomalies.
- Pathways
CEACAM5 involvement extends to immune response regulation and cell adhesion pathways. It interacts functionally with proteins like E-cadherin in these pathways which contribute to maintaining epithelial integrity. These pathways are critical for normal tissue maintenance and immune system function especially in mucosal surfaces where pathogen entry occurs. Understanding CEACAM5 interactions provides insight into cellular communication and adhesion mechanisms.
- Associated diseases and disorders
CEACAM5 is associated with colorectal cancer and lung adenocarcinoma. Its overexpression and release into the bloodstream make it a popular biomarker for these diseases. CEACAM5 is used in clinical applications such as CEA ELISA assays for cancer detection and monitoring. In colorectal cancer CEACAM5 interacts with proteins like CEACAM6 to promote tumor invasiveness and metastasis. Anti-CEACAM5 therapeutics including antibody-drug conjugates (anti-CEACAM5 ADC) are being developed to target and treat associated malignancies.
