Modified erythropoietin (EPO) polypeptide exhibiting increased proteolytic enzyme resistance and pharmaceutical composition thereof

摘要

Modified erythropoietin (EPO) polypeptides and other modified therapeutic polypeptides are provided. The EPO polypeptides and other therapeutic polypeptides are modified to exhibit physical properties and activities that differ from the unmodified EPO polypeptides and other unmodified therapeutic polypeptides, respectively. Nucleic acid molecules encoding these polypeptides also are provided. Also provided are methods of treatment and diagnosis using the polypeptides.
