Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
Contributes to the transcriptional repression of cholesterol 7-alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in bile acid synthesis. Probably inactive as a glycosidase. Increases the ability of FGFR1 and FGFR4 to bind FGF21.

Deletion of the D1 and the D1-D2 linker (the D1/linker region) from FGFR1c led to beta-Klotho-independent receptor activation by FGF21, suggesting that there may be a direct interaction between FGF21 and the D1/linker region-deficient FGFR1c.PMID:22248288
Polymorphism KLB rs4975017 may influence the colonic transit response to colesevelam in female patients with irritable bowel syndrome with diarrhea.PMID:22271411

High expression of Klotho is associated with ovarian disease progressionPMID:18259951
Both FGF23 and FGF21 require intact alpha or betaKlotho for signaling, respectively, whereas FGF19 can signal through a Klotho chimera consisting of the N terminus of alphaKlotho and the C terminus of betaKlotho.PMID:18829467
These data demonstrate that the C-terminus of FGF21 is critical for binding to beta-Klotho and the N-terminus is critical for fibroblast growth factor receptor (FGFR) activation.PMID:19059246
