MGI Phenotype

FUNCTION: 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 identified in retinal pigment epithelium (RPE) and analysis of the RPE transcriptome reveals that this gene expression appears late during development of chick embryo.
