Abstract
A non-naturally occuring Factor IX protein having an amino acid substitution at amino acid position 338 is provided. Preferred substitutions include the substitution of analanine, leucine, or valine for the arginine at amino acid position 338. Factor IX of the present invention is non-naturally occuring (e.g., does not contain only an arginine to proline substitution at amino acid position 338). Factor IX proteins of the invention are useful for facilitating blood clotting in subjects in need thereof, such as subjects afflicted with hemophilia B. Pharmaceutical formulations comprising Factor IX of the invention are provided, along with nucleic acids encoding the factor and vectors containing such nucleic acids.
