Abstract

Novel polypeptides, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed for zcytor17, a novel 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 zcytor17, are located on chromosome 5, 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.

Claims

1. An isolated polynucleotide encoding a monoclonal antibody or antigen binding fragment thereof that specifically binds to a fragment of a polypeptide consisting of amino acid residues 20-732 of SEQ ID NO:

2, wherein said fragment consists of amino acid residues 228-519 of SEQ ID NO;

2.

2. The isolated polynucleotide of claim 1, wherein the antigen binding fragment is a Fab, a F(ab′

)₂ or a single chain antibody.

3. The isolated polynucleotide of claim 1, wherein the monoclonal antibody or antigen binding fragment is chimeric.

4. The isolated polynucleotide of claim 1, wherein the monoclonal antibody or antigen binding fragment is humanized.

5. The isolated polynucleotide of claim 1, wherein the monoclonal antibody or antigen binding fragment is human.
