CLDN3

CLDN3

A gene on chromosome 7q11.23 that encodes claudin-3, an integral membrane protein of the claudin family, the members of which form part of the tight junction strands providing a continuous seal around cells and serving as a physical barrier to prevent solutes and water from passing freely into the interstitial space.
 
Molecular pathology
Claudin-3 has a low-affinity receptor for Clostridium perfringens enterotoxin.

Little to no expression was observed at any time point in either the biopaper or PET coculture systems for genes gap junction [beta]4 (GJB4), gap junction [beta]6 (GJB6), tight junction protein 3 (TJP3), and claudin 3 (CLDN3) (Table 2).
Expression of only endothelial, not epithelial, tight junction genes was confirmed though the use of negative controls TJP3 and CLDN3. TJP3, which codes for the tight junction protein zonal occludens-3 (ZO-3), is primarily expressed at epithelial tight junctions [19].
Many genes related to cell junctions (Tnfa, Tgf[beta], Actin, Tubulin, E-adherin, Tjpl, Tjp2, Tnfr, Integrin, Epsin, Pvrl, Rho Gtpase, Cadherin, Cldn3, Ras and A2m) diversely altered depending on pesticide doses and exposure times, are listed in Table S2 (http://dx.doi.
