General description

Claudin-2 (CLDN2) is one of the pore-forming claudins and is a member of the claudin family of proteins. It is present in the proximal tubules and the gene encoding it is localized on human chromosome Xq22.

Immunogen

CLDN2 (NP_065117, 29 a.a. ~ 80 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

Claudin-2 (CLDN2) controls paracellular permeability and maintains cell polarity in epithelial and endothelial cell sheets. In MDCK (madin-darby canine kidney cells), claudin-2 participates in the generation of aqueous pores with high conductance.

Physical form

Solution in phosphate buffered saline, pH 7.4
