HTF-1061 Recombinant Human KLF17 Protein $300

Recombinant Human KLF17 Protein

Product Name: Recombinant Human KLF17 Protein
Catalog #:  HTF-1061
Manufacture:  LD Biopharma, Inc.

KLF17 (ZNF393) 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. They are critical regulators of various cellular processes including reprogramming of differentiated cells to stem cells, erythropoiesis and cell survival. Moreover, some KLF family members have been implicated in tumor development. The murine homologue of KLF17 is believed to play a role in gametogenesis and early embryogenesis based on its expression in early embryos, testes and ovary, Recently, KLF17 has been demonstrated to be involved in the negatively regulation of breast cancer metastasis.

Full-length human KLF17 cDNA (389aa) 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.
