特徴

• 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. {ECO:0000250, ECO:0000269|PubMed:11062477, ECO:0000269|PubMed:11409890, ECO:0000269|PubMed:15040831, ECO:0000269|PubMed:16597617, ECO:0000269|PubMed:18282132}.
• Biological Activity:Fully biologically active when compared to standard. The ED50 as determined by thymidine uptake assay using FGF-receptors transfected BaF3 cells is less than 0.5ug/ml, corresponding to a specific activity of ＞ 2.0x10e3 IU/mg in the presence of 0.3 ug/ml of rMuKlotho and 10ug/ml of heparin.
