Description

This Recombinant Human Claudin-6 (CLDN6) is a high-quality, baculovirus-expressed protein fragment designed for developmental biology research. A key advantage is its expression in a Baculovirus system, which is superior for producing more complex eukaryotic proteins with proper folding compared to bacterial systems. The protein corresponds to a near-full-length fragment encompassing amino acids 2-220 of human CLDN6. It is engineered with both an N-terminal 10xHis tag and a C-terminal Twin-Strep tag, providing exceptional flexibility for two-step purification or various detection methodologies. The SDS-PAGE gel image confirms a high purity level (>85%), showing a sharp, predominant band at approximately 25 kDa. This recombinant CLDN6 protein, supported by its fully disclosed sequence, is an ideal tool for studying CLDN6's role in developmental processes, serving as a superior immunogen, a critical positive control, or for interaction studies requiring authentically folded protein domains.

Target Background

Function

Plays a major role in tight junction-specific obliteration of the intercellular space.; (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) entry into hepatic cells.

Antibodies recognizing native CLDN6 as displayed on cell surfaces and mediating complement-dependent cytotoxicity were elicited in vaccinated animals. The data suggest applications of CLDN6 displaying Virus-like particles in cancer immunotherapy. PMID: 29131519
these results suggest that Helicobacter pylori lipopolysaccharide induces TLR2 expression in the gastric adenocarcinoma cells, and that the longer the exposure to lipopolysaccharide, the greater the expression of TLR2 in the cell membrane; consequently the expression of claudin-4, -6, -7 and -9 also increases PMID: 29031421
Study provides evidence that high expression of CLDN6 confers chemoresistance on breast cancer which is mediated by GSTP1, the activity of which is regulated by p53. PMID: 29116019
CLDN6 enhances the chemoresistance to ADM via activating the AF-6/ERK signaling pathway and up-regulating cancer stem cell characters in MDAMB231 cells. PMID: 29159771
we demonstrated that the downregulation of CLDN6 is regulated through promoter methylation by DNMT1, which depends on the SMAD2 pathway, and that CLDN6 is a key regulator in the SMAD2/DNMT1/CLDN6 pathway to inhibit EMT, migration and invasion of breast cancer cells PMID: 28867761
In conclusion, this information from bioinformatics analysis will help future attempts to better understand CLDN6 regulation and functions. PMID: 28656265
high expression of CLDN 6 was observed in approx. 65% of the myxofibrosarcomas, whereas the benign soft tissue tumors did not show a high expression of CLDN 6. The expression of CLDN 6 in the myxofibrosarcomas was significantly higher than those of other tumor specimens. Among the myxofibrosarcomas, the high expression of CLDN 6 was correlated with high FNCLCC grades and high AJCC stages. PMID: 28476380
Results show that DNA methylation down-regulates CLDN6 expression through MeCP2 binding to the CLDN6 promoter, deacetylating H3 and H4, and altering chromatin structure, consequently promoting migratory and invasive phenotype in breast cancer cells. PMID: 27461117
