Background

Claudin-2 is a protein that in humans is encoded by the CLDN2 gene. By genomic sequence analysis, this gene is mapped to chromosome Xq22.3-q23. This gene product belongs to the claudin protein family whose members have been identified as major integral membrane proteins localized exclusively at tight junctions. Claudins are expressed in an organ-specific manner and regulate tissue-specific physiologic properties of tight junctions. By expression in a human intestinal epithelial cell line, it was determined that the intestine-specific homeodomain proteins CDX1 and CDX2 activated a reporter plasmid driven by the CLDN2 promoter.

Immunogen

A synthetic peptide corresponding to a sequence in the middle region of human Claudin 2/CLDN2, identical to the related mouse sequences.

Clonality

Polyclonal

Tissue Specificity

Detected in skin. In the cornea, it is detected in the epithelial basement membrane, the epithelial cells, and at a lower level in stromal cells. Stratified squamous epithelia. Found in hemidesmosomes. Expressed in cornea, oral mucosa, esophagus, intestine, kidney collecting ducts, ureter, bladder, urethra and thymus but is absent in lung, blood vessels, skeletal muscle and nerves.

Applications

Flow Cytometry, WB

Field of Research

Collagen, Cytoskeleton/ECM, ECM Proteins, Extracellular Matrix, Signal Transduction

Purification

Immunogen affinity purified.

Concentration

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Form

Lyophilized

Reconstitution

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Function

May play a role in the integrity of hemidesmosome and the attachment of basal keratinocytes to the underlying basement membrane. The 120 kDa linear IgA disease antigen is an anchoring filament component involved in dermal-epidermal cohesion. Is the target of linear IgA bullous dermatosis autoantibodies.
