Background: Claudins are cell-cell adhesion proteins expressed in tight junctions (TJs), the most common apical cell-cell adhesion. Claudin proteins regulate defense and barrier functions, as well as differentiation and polarity in epithelial and endothelial cells. Claudins are regulated through interactions with each other that are coordinated with other transmembrane tight junction proteins and cytosolic scaffold proteins. Of the 14 claudins expressed by the alveolar epithelium, claudin-3, claudin-4, and claudin-18 are the most prominent; each confers unique properties to alveolar barrier function. Aberrant expressions of claudins have been reported in various cancers. Claudin-4 mediates paracellular chloride transport and plays an important renal function through the reabsorption of filtered chloride. The CLDN4 gene is deleted in Williams-Beuren syndrome, leading to multi-systemic neurodevelopmental disorders. The protein acts as a high-affinity receptor for Clostridium perfringens enterotoxin (CPE) during infection by gram-positive Clostridial bacteria, which are responsible for food poisoning and gastrointestinal illnesses. Claudin 4 can be used as a marker for distinguishing malignant mesothelioma from lung cancer and uterine serous carcinoma. As a pancreatic cancer marker, Claudin-4 exhibits superior performance to BerEp4 staining. Claudin-4 may be overexpressed in ovarian cancer, and it accelerates cell migration and invasion in ovarian tumor cell lines.

Description: Recombinant Claudin-4 CHO K1 cell line stably expressing the full-length human Claudin-4 (accession number: NM_001305). Surface expression of hClaudin-4 was confirmed by flow cytometry. Each stable clonal cell line was selected for high level of hClaudin-4 expression compared to the parental CHO K1 cells.
