  • Publication number: 20070072244
    Abstract: This application is directed to a process of identifying a compound capable of modulating activity of a human ENDO180 receptor that comprises the steps of measuring the binding of the ENDO180 receptor to an interactor with which the ENDO180 receptor interacts specifically in vivo, in the absence or presence of a compound, and determining whether the binding of the ENDO180 receptor to the interactor is affected by the compound. This application is also directed to use of a compound identified by that process in the preparation of a medicament for therapy of disease, in particular fibrosis. This application also relates to the use of ENDO180 modulators in treatment of disease.

  • Publication number: 20050004065
    Abstract: The polynucleotide sequence of the 2-2-83 gene encodes the 2-2-83 protein. Hypoxic-associated pathologies may be regulated by administering an effective amount of a polynucleotide or protein of the present invention, or a direct or indirect biologically active product of enzymatic activity of the protein. Tumorigenesis may be inhibited by inhibiting the enzymatic activity of the protein of the present invention. The presence of a hypoxia-associated pathology may be diagnosed by screening for the reduced expression of the 2-2-83 gene.
