False colour image of Western blot : Anti-Claudin 4 antibody [EPRR17575] staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab210796 was shown to bind specifically to Claudin 4. A band was observed at 17 kDa in wild-type MCF7 cell lysates with no signal observed at this size in CLDN4 knockout cell line ab274946 (knockout cell lysate ab275004). To generate this image, wild-type and CLDN4 knockout MCF7 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Claudin-4 also known as CLDN4 is a protein essential for tight junctions which are critical in maintaining the permeability barrier of epithelial cells. The protein has a molecular mass of approximately 22 kDa. Claudin-4 expresses notably in epithelial cells of various tissues including the kidney lung and gastrointestinal tract. In addition to its presence in normal tissues claudin-4 can also exhibit heightened expression in certain cancerous tissues making it a subject of interest in oncology research.
Biological function summary

Claudin-4 plays a significant role in paracellular transport and cell polarity. By assembling into complexes with other claudins and tight junction proteins claudin-4 regulates the selective permeability and homeostasis across cell layers. It functions as a component of tight junction strands contributing to their barrier properties. Interaction with proteins such as occludin and ZO-1 further defines its role in tight junction structure and function.

Pathways

Claudin-4 participates in critical biological processes such as epithelial cell signaling and apoptosis regulation. It interfaces with the epithelial-to-mesenchymal transition (EMT) pathway where claudin-4 expression influences cellular adhesion and motility. Claudin-4 also interacts with related claudin proteins in these pathways contributing to structural arrangement and pathway signaling precision.

Claudin-4 has associations with several types of cancers including pancreatic and ovarian cancer. Its consistent overexpression in these conditions suggests its involvement in tumorigenesis and metastasis. In the context of ovarian cancer claudin-4 may interact with proteins such as mesothelin which plays a role in cell adhesion and tumor progression. Investigating claudin-4's involvement in cancer can provide insights into potential therapeutic targets and diagnostic markers.

靶点信息

Can associate with other claudins to regulate tight junction structural and functional strand dynamics (PubMed : 35773259, PubMed : 36008380). May coassemble with CLDN8 into tight junction strands containing anion-selective channels that convey paracellular chloride permeability in renal collecting ducts (By similarity) (PubMed : 36008380). May integrate into CLDN3 strands to modulate localized tight junction barrier properties (PubMed : 35773259, PubMed : 36008380). May disrupt strand assembly of channel-forming CLDN2 and CLDN15 and inhibit cation conductance (PubMed : 35773259, PubMed : 36008380). Cannot form tight junction strands on its own (PubMed : 35773259, PubMed : 36008380).
