WebMar 22, 2024 · This study aimed at discovering the role of the anti-aging protein α-klotho (KL), which is the co-receptor of fibroblast growth factor-23 (FGF23), in cardiac regeneration, fibrosis, and repair. We found that the anti-apoptotic function of soluble KL in isoproterenol-treated H9c2 cardiomyocytes was independent of FGF23 in vitro. WebIn the circulation, FGF23 may undergo further processing by plasminogen activators. Crystal structures show that the ectodomain of the cognate FGF23 receptor FGFR1c binds with the ectodomain of the co-receptor alpha-KLOTHO. The KLOTHO-FGFR1c double heterodimer creates a high-affinity binding site for the FGF23 C-terminus.

WebFGF23 acts locally within the bone and affects phosphate homeostasis in the kidney. FGF23 appears to be a true bone-derived hormone. The cofactor, Klotho, is required for FGF23 receptor binding and subsequent reduction of phosphate reabsorption in the renal proximal tubules.
