Product Specific Information

Phospho-Claudin 4 (Tyr208) Polyclonal Antibody detects endogenous levels of Claudin 4 only when phosphorylated at Tyr208.

Target Information

Claudin-4 belongs to the 20-member family of claudins, transmembrane cellular adhesion 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. Claudin-4 is a component of tight junction strands and may play a role in internal organ development and function during pre- and postnatal life. 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, and in other epithelial cancers. The Claudin-4 gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems.
