Entrez Gene Summary for FGF23 Gene

  • This gene encodes a member of the fibroblast growth factor family of proteins, which possess broad mitogenic and cell survival activities and are involved in a variety of biological processes. The product of this gene regulates phosphate homeostasis and transport in the kidney. The full-length, functional protein may be deactivated via cleavage into N-terminal and C-terminal chains. Mutation of this cleavage site causes autosomal dominant hypophosphatemic rickets (ADHR). Mutations in this gene are also associated with hyperphosphatemic familial tumoral calcinosis (HFTC). [provided by RefSeq, Feb 2013]

GeneCards Summary for FGF23 Gene

FGF23 (Fibroblast Growth Factor 23) is a Protein Coding gene. Diseases associated with FGF23 include hypophosphatemic rickets, autosomal dominant and tumoral calcinosis, hyperphosphatemic, familial. Among its related pathways are Signaling by GPCR and Immune System. GO annotations related to this gene include growth factor activity and type 1 fibroblast growth factor receptor binding. An important paralog of this gene is FGF21.

UniProtKB/Swiss-Prot for FGF23 Gene

  • Regulator 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.

Post-translational modifications for FGF23 Gene

  • 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.
  • Glycosylation at Thr 178
  • Modification sites at PhosphoSitePlus
