Description

General description

76.80 kDa calculated.

Carcinoembryonic antigen-related cell adhesion molecule 5 (UniProt: P06731; also known as Carcinoembryonic antigen, CEA, Meconium antigen 100, CD66e) is encoded by the CEACAM5 (also known as CEA) gene (Gene ID: 1048) in human. CEA is a cell surface heavily glycosylated homodimeric glycoprotein that plays a role in cell adhesion and in intracellular signaling. CEA molecules can either be transmembrane or GPI-linked and are differentially expressed between species. CEA is restricted to the apical face of intestinal epithelial cells in the adult, but it has more diffuse distribution during embryonic development and in tumors. It functions as a calcium independent adhesion molecule through homophilic and heterophilic interactions with CEACAM-1. CEA participates in diverse physiological processes, including cell adhesion, differentiation, proliferation, and survival, as well as in carcinogenesis and bacterial pathogenesis. CEA molecules from neighboring cells can interact via their respective extracellular N-terminal IgV-like domain and mediate cell-cell adhesion through trans-oligomerization. CEA is synthesized with a signal peptide (aa 1-34) and a propeptide region (aa 686-702) that are cleaved to produce the mature form. It has seven Ig-like domains. Two isoforms of CEA have been reported that are produced by alternative splicing. Clone M5A is a humanized monoclonal antibody that displays high specificity and sub-nanomolar affinity for tumor-associated CEA. (Ref. Yazaki, PJ et al., (2004). Protein Eng. Des Sel. 17(5);481-489.
