KLB /BKL(beta-klotho) is a single-pass, type III transmembrane protein that belongs to a the Klotho subfamily of the glycosyl hydrolase 1 family. KLB contains 2 glycosyl hydrolase 1 regions in the extracellular domain (ECD) and may have weak glycosidase activity towards glucuronylated steroids. However, KLB lacks essential active site Glu residues at positions 241 and 889.  KLB may contribute to the repression of expression of cholesterol 7-alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in bile acid synthesis. KLB interacts with FGFR1 and FGFR4 and enhances their abilities to bind FGF21. KLB also directly interacts with FGF19 and FGF21. KLB is preferentially expression in fat and liver and may be involved in carbohydrate metabolism.

Product Details

 

Gene Symbol: KLB; BKL; betaKlotho; beta-Klotho; klotho beta; b-Klotho

 

NCBI Gene ID: 125831

 

Uniprot Entry: Q86Z14

 

Construct Details: Full length human KLB/betaKlotho gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without an antibiotic selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 3135 (bp)
