app notes :
WB (1/500 - 1/1000), IH (1/100 - 1/200). Western blot analysis of Claudin 4 expression in DLD (A), SW480 (B), LS1034 (C), MIA (D), PaCa2 (E) whole cell lysates. Immunohistochemical analysis of Claudin 4 staining in human tonsil formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

ncbi summary :
The protein encoded by this intronless gene belongs to the claudin family. Claudins are integral membrane proteins that are components of the epithelial cell tight junctions, which regulate movement of solutes and ions through the paracellular space. This protein is a high-affinity receptor for Clostridium perfringens enterotoxin (CPE) and may play a role in internal organ development and function during pre- and postnatal life. This gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. [provided by RefSeq, Sep 2013]
uniprot summary :
Claudin-4: Plays a major role in tight junction-specific obliteration of the intercellular space. CLDN4 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region. Belongs to the claudin family. Protein type: Membrane protein, integral; Cytoskeletal; Membrane protein, multi-pass. Chromosomal Location of Human Ortholog: 7q11.23. Cellular Component: tight junction; apicolateral plasma membrane; integral to plasma membrane; apical plasma membrane; plasma membrane; basal plasma membrane; lateral plasma membrane. Molecular Function: identical protein binding; transmembrane receptor activity; structural molecule activity. Biological Process: female pregnancy; signal transduction; response to progesterone stimulus; calcium-independent cell-cell adhesion
