Summary: This gene encodes a member of the claudin family. Claudins are integral membrane proteins and components of tight junction strands. Tight junction strands serve as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets, and also play critical roles in maintaining cell polarity and signal transductions. The protein encoded by this gene is a low-affinity receptor for clostridium perfringens enterotoxin (CPE) produced by the bacterium Clostridium perfringens, and the interaction with CPE results in increased membrane permeability by forming small pores in plasma membrane. This protein is highly overexpressed in uterine carcinosarcoma. This protein is also predominantly present in brain endothelial cells, where it plays a specific role in the establishment and maintenance of blood brain barrier tight junction morphology.

In the hepatobiliary system, Cldn3 functions as a paracellular barrier for phosphate ions, and that dysfunction of this barrier causes significant dysfunctional biliary metabolism of phosphorus, which leads to the formation of calcium phosphate cores for cholesterol gallstones.

Critical role of claudin-3 in water barrier function was confirmed in Cldn3-/- and Cldn3+/- mice and those with experimentally decreased claudin-3. Those results show the crucial role of claudin-3 in preventing sweat gland leakage and suggest that the pathogenesis of dermatoses accompanied by hypohidrosis involves abnormally decreased claudin-3.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
