  • Patent number: 9260525
    Abstract: Antibody molecules that specifically bind to one or more isoforms expressed and/or associated with oncogenic phenotypes in a hyperproliferative cell (e.g., a cancerous or tumor cell) are disclosed. The isoform-binding antibody molecules can be used to treat, prevent and/or diagnose cancerous conditions and/or disorders. Methods of using the isoform-binding molecules to selectively detect oncogenic isoforms, to reduce the activity and/or induce the killing of a hyperproliferative cell expressing an oncogenic isoform in vitro, ex vivo or in vivo are also disclosed. Diagnostic and/or screening methods and kits for evaluating the function or expression of an oncogenic isoform are also disclosed.
    Type: Grant

  • Patent number: 7235374
    Abstract: Methods for detecting G-protein coupled receptor (GPCR) activity; methods for assaying GPCR activity; and methods for screening for GPCR ligands, G-protein-coupled receptor kinase (GRK) activity, and compounds that interact with components of the GPCR regulatory process are described. Included are methods for expanding ICAST technologies for assaying GPCR activity with applications for ligand fishing, and agonist or antagonist screening. These methods include: engineering seronine/threonine phosphorylation sites into known or orphan GPCR open reading frames in order to increase the affinity of arrestin for the activated form of the GPCR or to increase the reside time of arrestin on the activated GPCR; engineering mutant arrestin proteins that bind to activated GPCRs in the absence of G-protein coupled receptor kinases which may be limiting; and engineering mutant super arrestin proteins that have an increased affinity for activated GPCRs with or without phosphorylation.
