Background Information

Claudin 23 (CLDN23) belongs to the large claudin family of proteins, which are tetraspan transmembrane proteins of tight junctions (PMID: 12736707; 18036336). Claudins exhibit specific patterns of expression in different tissues. Human CLDN23 mRNA was expressed in germinal center B cells, placenta, stomach as well as in colon tumor (PMID: 12736707). CLDN23 has been reported as a candidate tumor suppressor gene implicated in intestinal-type gastric cancer (PMID: 12736707).
