Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B IP
Claudin-4 belongs to the 20-member family of claudins, transmembrane proteins localized at epithelial and endothelial tight junctions. Claudins demonstrate distinct, tissue-specific expression patterns, and are essential components of tight junction charge-specific channels that regulate paracellular ion flux. The overexpression of Claudin-4 has been shown to decrease paracellular electrical conductance due to a selective decrease in Na+ permeability, with no significant decrease in Cl– permeability. In ovarian carcinoma cells, Claudin-3 and Claudin-4 exhibit upregulation at both mRNA and protein levels. Claudin-4 is also overexpressed in pancreatic cancer tissues and cell lines.
