Patent number: 7427498Abstract: 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.Type: GrantFiled: June 8, 2004Date of Patent: September 23, 2008Assignee: Universite De MontrealInventors: Philippe Crine, Guy Boileau
