CC -!- FUNCTION: Regulator of phosphate homeostasis (PubMed:11062477). CC Inhibits renal tubular phosphate transport by reducing SLC34A1 levels CC (PubMed:11409890). Up-regulates EGR1 expression in the presence of KL CC (By similarity). Acts directly on the parathyroid to decrease PTH CC secretion (By similarity). Regulator of vitamin-D metabolism CC (PubMed:15040831). Negatively regulates osteoblast differentiation and CC matrix mineralization (PubMed:18282132). {ECO:0000250|UniProtKB:Q8VI82, CC ECO:0000269|PubMed:11062477, ECO:0000269|PubMed:11409890, CC ECO:0000269|PubMed:15040831, ECO:0000269|PubMed:16597617, CC ECO:0000269|PubMed:18282132}. CC -!- SUBUNIT: Interacts with FGFR1, FGFR2, FGFR3 and FGFR4 CC (PubMed:16597617). Affinity between fibroblast growth factors (FGFs) CC and their receptors is increased by KL and heparan sulfate CC glycosaminoglycans that function as coreceptors (By similarity). CC {ECO:0000250|UniProtKB:Q9EPC2, ECO:0000269|PubMed:16597617}. CC -!- INTERACTION: CC Q9GZV9; P11362: FGFR1; NbExp=2; IntAct=EBI-6594125, EBI-1028277; CC Q9GZV9; O35082: Kl; Xeno; NbExp=5; IntAct=EBI-6594125, EBI-1570828; CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:16638743}. CC Note=Secretion is dependent on O-glycosylation. CC -!- TISSUE SPECIFICITY: Expressed in osteogenic cells particularly during CC phases of active bone remodeling. In adult trabecular bone, expressed CC in osteocytes and flattened bone-lining cells (inactive osteoblasts). CC {ECO:0000269|PubMed:12952917}. CC -!- PTM: Following secretion this protein is inactivated by cleavage into a CC N-terminal fragment and a C-terminal fragment. The processing is CC effected by proprotein convertases. {ECO:0000269|PubMed:11157998, CC ECO:0000269|PubMed:12130585, ECO:0000269|PubMed:15268897}. CC -!- PTM: O-glycosylated at Thr-171 and Thr-178 by GALNT3 and glycosylation CC of Thr-178 requires previous glycosylation at Thr171. Glycosylation is CC necessary for secretion; it blocks processing by proprotein convertases CC when the O-glycan is alpha 2,6-sialylated. Competition between CC proprotein convertase cleavage and block of cleavage by O-glycosylation CC determines the level of secreted active FGF23. CC {ECO:0000269|PubMed:16638743, ECO:0000269|PubMed:31932717}. CC -!- PTM: Phosphorylation at Ser-180 mediated by FAM20C slows down CC glycosylation at Thr-178 notably. {ECO:0000269|PubMed:31932717}. CC -!- DISEASE: Hypophosphatemic rickets, autosomal dominant (ADHR) CC [MIM:193100]: A disease characterized by isolated renal phosphate CC wasting, hypophosphatemia, and inappropriately normal 1,25- CC dihydroxyvitamin D3 (calcitriol) levels. Patients frequently present CC with bone pain, rickets, and tooth abscesses. CC {ECO:0000269|PubMed:11062477, ECO:0000269|PubMed:11409890, CC ECO:0000269|PubMed:16638743}. Note=The disease is caused by variants CC affecting the gene represented in this entry. CC -!- DISEASE: Tumoral calcinosis, hyperphosphatemic, familial, 2 (HFTC2) CC [MIM:617993]: A form of hyperphosphatemic tumoral calcinosis, a rare CC autosomal recessive metabolic disorder that manifests with CC hyperphosphatemia and massive calcium deposits in the skin and CC subcutaneous tissues. Some patients have recurrent, transient, painful CC swellings of the long bones associated with the radiographic findings CC of periosteal reaction and cortical hyperostosis and absence of skin CC involvement. {ECO:0000269|PubMed:15590700, ECO:0000269|PubMed:16030159, CC ECO:0000269|PubMed:16151858, ECO:0000269|PubMed:24680727}. Note=The CC disease is caused by variants affecting the gene represented in this CC entry. CC -!- SIMILARITY: Belongs to the heparin-binding growth factors family. CC {ECO:0000305}.
