Product Specific Information
PA5-16875 targets Claudin 4 in IHC (P) applications and shows reactivity with human and mouse samples.
The PA5-16875 immunogen is a synthetic peptide derived from the C-terminus of human Claudin-4.
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. Overexpression of Claudin-4 decreases 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.
