Additional Info
| Post Translational Modifications | 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 at Thr-171 and Thr-178 by GALNT3 and glycosylation of Thr-178 requires previous glycosylation at Thr171. 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. Phosphorylation at Ser-180 mediated by FAM20C slows down glycosylation at Thr-178 notably. |
| Function | Regulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Regulator of vitamin-D metabolism. Negatively regulates osteoblasts differentiation and matrix mineralization. Acts directly on the parathyroid to decrease PTH secretion. Up-regulates EGR1 expression in the presence of KL. |
