WebFeb 20, 2009 · The co-receptor is βKlotho, a Klotho-related protein sharing ~40% amino acid sequence identity . βKlotho is expressed predominantly in the liver and white adipose tissue, while Klotho is expressed mainly in the kidney. βKlotho also forms a complex with several FGF receptor isoforms and significantly increases their affinity to FGF15/19 and ... WebIt is also shown that FGF1 binding stimulates assembly of βKlotho and FGFR1c on cell membranes, resulting in endocytosis and degradation of βKlotho. We conclude that heparin or HSPG is essential for FGF21 signaling and for regulation of βKlotho cellular stability by acting as a coligand of FGFR1c.
