Gene Information

human ... CLDN5(7122)

General description

Claudin-5 (CLDN5) is encoded by the gene mapped to human chromosome 22q11.21. The encoded protein a 23kDa, four-transmembrane protein. It is mainly expressed in endothelial cells forming part of the blood-brain barrier (BBB).

Immunogen

synthetic peptide corresponding to a sequence at the C-terminus of human claudin-5, conjugated to KLH. The corresponding sequence is highly conserved in mouse claudin-5 (single amino acid substitution) and in rat claudin-5 (89% identity).

Biochem/physiol Actions

Claudin-5 (CLDN5), as an essential component of blood-brain barrier (BBB), plays a vital role in regulating the homeostasis of the central nervous system. Mutation in the gene increases the risk of susceptibility to schizophrenia. Overexpression of the gene is associated with the progression of pancreatic ductal adenocarcinomas. Loss of CLDN5 in cardiomyocytes and endothelial cells is one of the main reason behind human heart failure. Hence, early usage of CLDN5 can be considered as a potential therapeutic target for heart failure.
Claudin-5 has been shown to be overexpressed in various tumors including lung adenocarcinomas but undetectable in squamous cells cell carcinomas.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
