Recombinant Human KLF3 Protein

Product Name: Recombinant Human KLF3 Protein
Catalog #:  HTF-1067
Manufacture:  LD Biopharma, Inc.

Human KLF3 is a member of Sp/KLF zinc finger protein family with diverse functions. Krüppel-like factor (KLF) family members can function as either activators or repressors depending on the promoters they bind and the cellular proteins they interact with. Human KLF3, when interacts with Ctbp becomes a transcriptional repressor for regulating KLF1 gene transcription in erythroid cell differentiation. Recent data indicated that KLF3 is a critical regulator for B cell development.

Full-length human KLF3 cDNA (345aa) was constructed with codon optimization 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. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
