FGF-23 (Fibroblast growth factor 23) is a regulator of phosphate homeostasis. It upregulates EGR1 expression in the presence of KLBy. Acts directly on the parathyroid to decrease PTH secretion. Regulates the vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization. Defects in FGF-23 are the cause of autosomal dominant hypophosphataemic rickets (ADHR) and of hyperphosphatemic familial tumoral calcinosis (HFTC).
Biological Activity:Activates ERK and FRS2alpha phosphorylation in Klotho expressing cells.
Sequence:Signal peptide and human FGF-23 (aa 1-251) are fused at the C-terminus to the Fc portion of human IgG1.
