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.

Abstract: The present invention relates to polynucleotide and polypeptide molecules for zcyto20, zcyto21, zcyto22, zycto24, and zcyto25 proteins which are most closely related to interferon-? at the amino acid sequence level. The receptor for this protein family is a class II cytokine receptor. The present invention includes methods of reducing viral infections and increasing monocyte counts. The present invention also includes antibodies to the zcyto20 polypeptides, and methods of producing the polynucleotides and polypeptides.

Abstract: The present invention relates to polynucleotide and polypeptide molecules for Zcyto21, an interferon-like protein, which is most closely related to interferon-? at the amino acid sequence level.

Abstract: The expression vectors and methods using an E. coli expression system for the large scale production of IL-29 are described. The vectors utilize the IL-29 coding sequence with specific changes in nucleotides in order to optimize codons and mRNA secondary structure for translation in E. coli. Also included are methods of producing, purifying and pegylating an IL-29 polypeptide.

Abstract: Methods for treating patients with cancer and autoimmune disorders using IL-28 and IL-29 molecules. The IL-28 and IL-29 molecules include polypeptides that have homology to the human IL-28 or IL-29 polypeptide sequence and proteins fused to a polypeptide with IL-28 and IL-29 functional activity. The molecules can be used as a monotherapy or in combination with other known cancer and/or autoimmune therapeutics.

Abstract: Homogeneous preparations of IL-28A, IL-28B, and IL-29 have been produced by mutating one or more of the cysteine residues in the polynucleotide sequences encoding the mature proteins. The cysteine mutant proteins can be shown to either bind to their cognate receptor or exhibit biological activity. One type of biological activity that is shown is an antiviral activity.
