  • Publication number: 20110091876
    Abstract: Novel polypeptides, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed for zcytor19, a novel class II cytokine receptor. The polypeptides may be used within methods for detecting ligands that stimulate the proliferation and/or development of hematopoietic, lymphoid and myeloid cells in vitro and in vivo. Ligand-binding receptor polypeptides can also be used to block ligand activity in vitro and in vivo. The polynucleotides encoding zcytor19, are located on chromosome 1p36.11, and can be used to identify a region of the genome associated with human disease states. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.

  • Publication number: 20110081346
    Abstract: Disclosed is a newly identified B7 family member, zB7H6, which functions as a counter-receptor for the NK cell triggering receptor, NKp30. Methods and compositions for modulating NKp30-mediated NK cell activity based on the interaction of zB7H6 with NKp30, as well as related screening methods, are also disclosed. Further disclosed are anti-zB7H6 antibodies as well as antibody-drug conjugates comprising an anti-zB7H6 antibody conjugated to a therapeutic agent, including methods for using such antibodies and antibody-drug conjugates to exert therapeutic effects against zB7H6-expressing cells.

  • Publication number: 20110027263
    Abstract: A soluble receptor to IL-20 having two polypeptide subunits, IL-20RA (formerly called ZcytoR7) and IL-20RB (formerly called DIRS1). The two subunits are preferably linked together. In one embodiment one subunit is fused to the constant region of the light chain of an immunoglobulin, and the other subunit is fused to the constant region of the heavy chain of the immunoglobulin. The light chain and the heavy chain are connected via a disulfide bond.
