Background: CEACAM-20

Carcinoembryonic antigen-related cell adhesion molecule-20 (CEACAM-20) is a member of the CEACAM subfamily of glycoproteins in the immunoglobulin (Ig) superfamily primarily found in mammals. Mature mouse CEACAM-20 consists of an extracellular domain (ECD) with a truncated IgV-like N domain, unique among CEACAMs, and four IgC2-like domains, a transmembrane domain, and a cytoplasmic domain (1-5). The cytoplasmic domain is unusually long compared to most other CEACAMs and is predicted to contain four tyrosine phosphorylation sites, two of which correspond to the immune-receptor tyrosine-based activation motif (ITAM) (2, 3). The ECD of mouse CEACAM-20 shares 59% and 82% amino acid sequence identity to human and rat CEACAM-20, respectively. CEACAM proteins, along with the closely related pregnancy-specific glycoproteins (PSGs), have been linked to numerous intercellular-adhesion and intracellular signaling processes including cell adhesion, growth, and recognition, differentiation, angiogenesis, apoptosis as well as pathogen transmission, tumorigenesis, and fetal–maternal interactions (5, 7, 8). CEACAM-20 expression is limited to the reproductive system and the intestinal tract, with the highest levels of expression found in the small intestine and prostate (2, 3). An in vitro model of human prostate morphogenesis showed that CEACAM-20 is co-expressed with CEACAM-1 and plays a critical role in the formation of prostate organoids, making it a marker for prostate cancer (2). Although the exact mechanism is not fully understood, CEACAM-20 may promote the proliferation of intestinal epithelial cells (IECs) (9). There is evidence suggesting CEACAM-20 can induce the production of chemokines like interleukin (IL)-8 and stimulate inflammatory responses in colitis and Crohn's disease (6). CEACAM-20 is also thought be act as a physiological substrate for SAP-1 in the intestinal epithelium (10).
