Recombinant Human CBY1 Protein

Product Name: Recombinant Human CBY1 Protein
Catalog #:  HTF-1533
Manufacture:  LD Biopharma, Inc.

Beta-catenin is a transcriptional activator and oncoprotein involved in the development of several cancers. The protein encoded by human protein Chibby homolog-1 (CBY1) gene interacts directly with the C-terminal region of beta-catenin, inhibiting oncogenic beta-catenin-mediated transcriptional activation, such as Wnt pathway by competing with transcription factors for binding to beta-catenin. Recent data indicated that CBY1 also playa a role in regulating the intracellular trafficking of polycystin-2/PKD2 and possibly of other intracellular proteins. Promotes adipocyte and cardiomyocyte differentiation. Two transcript variants encoding different isoforms have been found for this gene.

Full-length human CBY1 cDNA (125aa) was constructed with codon optimization technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. It was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
