Recombinant Human TGIF2-11R Protein

Product Name: Recombinant Human TGIF2-11R Protein
Catalog #:  HTF-2055
Manufacture:  LD Biopharma, Inc.

The protein encoded by human TGIF2 gene is a transcriptional repressor, which probably repress transcription by binding directly the 5'-CTGTCAA-3' DNA sequence or by interacting with TGF-beta activated SMAD proteins. Probably represses transcription via the recruitment of histone deacetylase proteins. TGIF2 is widely expressed. It highly expressed in heart, kidney, testis and weakly expressed in brain and prostate. .Recent data indicated that regulating TGIF2 activities may be useful to stepwise reprogramming of liver cells to a pancreatic progenitor state.

Full-length human TGIF2 cDNA ( 508aa ) was constructed with codon optimization using gene synthesis technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal and 11 arginine (11R tag) at its C-terminal. It was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
