| Intruduction: | Human Jun dimerization protein 2 (JDP2) gene encodes a basic leucine zipper (bZIP) protein displaying a high degree of homology with the stress inducible transcription factor, ATF3. Both proteins bind to cAMP and TPA response elements and repress transcription by multiple mechanisms. JDP2 was demonstrated to be direct binder for ATF3 with HDACs 1, 2–6 and 10. JDP2 has antagonist activity for cJun, recent data indicated that by inhibiting cJun activities will enhancer iPS generation efficiency in vitro. Full-length human JDP2 cDNA (162 aa, Isoform-I) was constructed with codon optimization by gene synthesis and expressed with N-terminal 29aa Tag and C-terminal flexible linker domain & eleven arginine (11R Tag) as membrane penetration domain to enable penetration across the plasma membrane of mammalian cells. This protein is expressed in E Coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. |
