ABSTRACT:
Provided are nucleic acids encoding erythropoietin (EPO) proteins and having modifications in the 5' and 3' noncoding sequences relative to the corresponding sequences in native EPO DNA. The invention also relates to the use of such nucleic acids to produce EPO proteins, which may have altered activity as compared to EPO proteins expressed from nucleic acids having native 5' and 3' sequences.
