    摘要: The object of the present invention is to increase PHEX activity to improve the osteogenic process in a mammal where this process has been diminished due to pathology or a condition that require osteogenesis. Osteocalcin is an endogenous inhibitor of the PHEX activity. Therefore, the identification of a substance capable of potentiating PHEX activity by preventing the inhibitory action of endogenous inhibitors will improve osteogenesis. Since PHEX is generally associated with the growth plane of bone or teeth and the absence of osteocalcin is associated with increased bone mass, potentiation of PHEX activity can promote bone growth. Increased PHEX activity can also be obtained by administration of the enzyme itself.

    摘要: This invention relates to a soluble form of PHEX, PHEX being a type II integral membrane glycoprotein. This enzyme is the gene product of a phosphate-regulating gene with homologies to endopeptidases on the X chromosome. To produce a soluble form of PHEX, the transmembrane anchor domain has been modified to encode a signal peptidase coding sequence. The soluble PHEX therefore comprises the active ectodomain. An inactive mutant of PHEX is also an object of this invention. Both soluble and inactive mutant forms of PHEX can be used to screen ligands to PHEX. These ligands can also be used as substrates or inhibitors of PHEX. PHEX being phosphaturic, an inhibitor thereof will be used to treat phosphaturia and/or hypophosphatemia. On the opposite, a substrate for PHEX or PHEX itself can be used to treat hyperphosphatemia.
