Application Abreviews Notes
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 27, 38 kDa (predicted molecular weight: 28 kDa). When using mouse brain lysate:


  • FunctionRegulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Upregulates EGR1 expression in the presence of KL (By similarity). Acts directly on the parathyroid to decrease PTH secretion (By similarity). Regulator of vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization.
  • Tissue specificityExpressed in osteogenic cells particularly during phases of active bone remodeling. In adult trabecular bone, expressed in osteocytes and flattened bone-lining cells (inactive osteoblasts).
  • Involvement in diseaseDefects in FGF23 are the cause of autosomal dominant hypophosphataemic rickets (ADHR) [MIM:193100]. ADHR is characterized by low serum phosphorus concentrations, rickets, osteomalacia, leg deformities, short stature, bone pain and dental abscesses.
    Defects in FGF23 are a cause of hyperphosphatemic familial tumoral calcinosis (HFTC) [MIM:211900]. HFTC is a severe autosomal recessive metabolic disorder that manifests with hyperphosphatemia and massive calcium deposits in the skin and subcutaneous tissues.
  • Sequence similaritiesBelongs to the heparin-binding growth factors family.
  • Post-translational
    Following secretion this protein is inactivated by cleavage into a N-terminal fragment and a C-terminal fragment. The processing is effected by proprotein convertases.
    O-glycosylated by GALT3. Glycosylation is necessary for secretion; it blocks processing by proprotein convertases when the O-glycan is alpha 2,6-sialylated. Competition between proprotein convertase cleavage and block of cleavage by O-glycosylation determines the level of secreted active FGF23.
  • Cellular localizationSecreted. Secretion is dependent on O-glycosylation.

    Predicted band size : 28 kDa
    Observed band size : 27 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 38 kDa. We are unsure as to the identity of these extra bands.
