1. An expression vector comprising the following operably linked elements:
- a) a first transcription promoter, a first DNA segment encoding a first cytokine receptor polypeptide comprising amino acid residues 33-662 of SEQ ID NO;
5; and
a first transcription terminator, andb) a second transcription promoter, a second DNA segment encoding a second cytokine receptor polypeptide comprising amino acid residues 28-979 of SEQ ID NO;
7; and
a second transcription terminator;
wherein the first cytokine receptor polypeptide and the second cytokine receptor polypeptide form a heterodimeric cytokine receptor, andwherein the heterodimeric cytokine receptor binds to a ligand comprising amino acid residues 27-164 of SEQ ID NO;

Abstract
Novel polypeptide combinations, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed for zcytor17-containing multimeric or heterodimer cytokine receptors that may be used as novel cytokine antagonists, and within methods for detecting ligands that stimulate the proliferation and/or development of hematopoietic, lymphoid and myeloid cells in vitro and in vivo. The present invention also includes methods for producing the multimeric or heterodimeric cytokine receptor, uses therefor and antibodies thereto.
