  • Patent number: 7186805
    Abstract: The polypeptides, and the polynucleotides encoding for them, described herein are IL-21 antagonists that bind with specificity and exhibit an EC50 that is not detectable in receptor binding studies. These molecules have mutations in the D helix of the IL-21 molecule, and can be used to inhibit the activity of IL-21 with its cognate receptor.
