Abstract
The present invention relates to zcytor17lig polynucleotide, polypeptide and anti-zcytor17 antibody molecules. The zcytor17lig is a novel cytokine. The polypeptides may be used within methods for stimulating the immune system, and proliferation and/or development of hematopoietic cells in vitro and in vivo. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.
Claims20

- (a) amino acid residues 31 to 163 as shown in SEQ ID NO:11;
- or
- (b) amino acid residues 1 to 163 as shown in SEQ ID NO:11.
An isolated antigenic polypeptide comprising a sequence of at least 30 contiguous amino acid residues of SEQ ID NO:
- 11, wherein the antigenic polypeptide comprises the amino acid sequence selected from:
- (a) amino acid residues 34 to 39 of SEQ ID NO:
- 11;
- (b) amino acid residues 46 to 51 of SEQ ID NO:
- 11;
