Swiss-port # P06731 Human Carcinoembryonic antigen-related cell adhesion molecule 5 |
|---|---|
| Gene Symbol | CEACAM5 |
| Gene Full Name | carcinoembryonic antigen-related cell adhesion molecule 5 |
| Background | This gene encodes a cell surface glycoprotein that represents the founding member of the carcinoembryonic antigen (CEA) family of proteins. The encoded protein is used as a clinical biomarker for gastrointestinal cancers and may promote tumor development through its role as a cell adhesion molecule. Additionally, the encoded protein may regulate differentiation, apoptosis, and cell polarity. This gene is present in a CEA family gene cluster on chromosome 19. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015] |
| Function | Cell surface glycoprotein that plays a role in cell adhesion, intracellular signaling and tumor progression (PubMed:2803308, PubMed:10910050, PubMed:10864933). 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. [UniProt] |
| Cellular Localization | Cell membrane; Lipid-anchor, GPI-anchor. [UniProt] |
| Calculated MW | 77 kDa |
| PTM | Complex immunoreactive glycoprotein with a MW of 180 kDa comprising 60% carbohydrate. [UniProt] |
