Abstract: The invention provides polypeptides having IgG Fc regions with amino acid modifications that result in the polypeptides exhibiting altered Fc effector functions.

Abstract: The invention provides humanized and chimeric anti-CD20 antibodies for treatment of CD20 positive malignancies and autoimmune diseases.

Abstract: IGFBP-3 fusion proteins are provided that are useful, for example, in cell-based assays, as IGF antagonists, and in mapping IGF-I and IGF-II binding sites on other molecules such as wild-type IGFBP-3 and IGF agonist peptides identified by phage display. Methods for making such fusion proteins are also provided.

Abstract: Humanized and variant anti-VEGF antibodies and various uses therefor are disclosed. The anti-VEGF antibodies have strong binding affinities for VEGF; inhibit VEGF-induced proliferation of endothelial cells in vitro; and inhibit tumor growth in vivo.

Abstract: IGF-I and insulin variants are provided that selectively bind to IGFBP-1 or IGFBP-3. These agonist variants are useful, for example, to improve the half-lives of IGF-I and insulin, respectively.

Abstract: Human growth hormone variants and their nucleic acids are disclosed wherein the amino acid residues at positions 10, 14, 18, 21, 167, 171, 174, 176 and 179 have been replaced with other amino acids. Also claimed are vectors and host cells comprising these human growth hormone variants as well as processes for their preparation.

Abstract: Growth hormone participates in the regulation of normal growth and development processes. The binding affinity of growth hormone for its target receptors is dependent upon the interaction of site 1 and site 2 domains of growth hormone with the target receptor. Embodiments of the present invention include site 1 variants of human growth hormone which bind to target receptors with a different affinity than that of the native hormone. Embodiments of the invention further include components for the production of isolated human growth hormone variants using a host cell/vector expression system.

Abstract: Human growth hormone variants are disclosed wherein the lysine at position 41 and/or the leucine at position 45 of native human growth hormone, numbered from the mature N-terminus of native human growth hormone, has been replaced with another amino acid. Also claimed are combination variants that have a higher binding affinity to the growth hormone receptor than wild-type human growth hormone.
