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 mouse FGF-23 (aa 1-251) are fused at the C-terminus to the Fc portion of human IgG1.

Molecular Weight:
~50kD (SDS-PAGE, full-length) FGF23 is cleaved between arg179 and ser 180 (~40kD).
