Recombinant Human FABP6 Protein

Product Name: Recombinant Human FABP6 Protein
Catalog #:  hRP-1846
Manufacture:  LD Biopharma, Inc.

The fatty-acid-binding proteins (FABPs) are a family of transport proteins for fatty acids and other lipophilic substances such as eicosanoids and retinoids. These proteins are thought to facilitate the transfer of fatty acids between extra- and intracellular membranes. Some family members are also believed to transport lipophilic molecules from outer cell membrane to certain intracellular receptors such as PPAR. Levels of fatty-acid-binding protein have been shown to decline with ageing in the mouse brain, possibly contributing to age-associated decline in synaptic activity. FABP6 (Gastrotropin) and FABP1 protein are mainly expressed in human liver (the ileal fatty acid binding protein) are also able to bind bile acids. FABP6 plays an important role in regulation of cholesterol uptake in liver.

Full-length of human FABP6 cDNA (127aa, derived from BC022489) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein 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.
