| Gene Summary |
Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. These junctions are comprised of sets of continuous networking strands in the outwardly facing cytoplasmic leaflet, with complementary grooves in the inwardly facing extracytoplasmic leaflet. The protein encoded by this gene, a member of the claudin family, is an integral membrane protein and a component of tight junction strands. Loss of function mutations result in neonatal ichthyosis-sclerosing cholangitis syndrome. [provided by RefSeq, Jul 2008] |

| Function |
Claudin-1 is a member of the transmembrane protein family claudins located in cell-cell tight junctions and it acts as a co-receptor for HCV entry into hepatic cells. Claudins are abundant in luminal epithelial sheets where they maintain epithelial cell polarity. Claudin-1 is expressed in most tissues such as bladder, fallopian tube, liver, pancreas, prostate, and skin. |
