Abstract
The application discloses Factor VIII polypeptides comprising internal deletions of amino acids within the area of residues 741 to 1689, wherein the thrombin cleavage sites at about 741 and about 1689 are present, and a site at about 1648 is not present, as compared to human Factor VIII.
Claims11
A Factor VIII polypeptide comprising an internal deletion of amino acids from residue 741 to residue 1688, with reference to full-length human factor VIII amino acid sequence of SEQ ID NO:1, wherein the internal deletion is amino acid positions 746 to 1649, 746 to 1652, 746 to 1655, 758 to 1649, 758 to 1652, 758 to 1655, 765 to 1649, 765 to 1652, 765 to 1655, 748 to 1658, 755 to 1658, 762 to 1658, 769 to 1658, 776 to 1658, or 783 to 1658.
A Factor VIII polypeptide comprising an internal deletion of one or more amino acids from residue 741 to residue 1688, with reference to full-length human factor VIII amino acid sequence of SEQ ID NO:
- 1, wherein praline at position 739 is replaced by another amino acid.
A Factor VIII polypeptide comprising an internal deletion of amino acids from residue 746 to residue 1655, with reference to full-length human factor VIII amino acid sequence of SEQ ID NO:1, wherein the internal deletion is amino acid positions 746 to 1649, 746 to 1652, 746 to 1655, 758 to 1649, 758 to 1652, 758 to 1655, 765 to 1649, 765 to 1652, 765 to 1655, further comprising tripeptide sequence (Asn-X-Thr or Asn-X-Ser where X can be any amino acid) encompassing fusion sites between Asn amino acid at positions 745, 757, or 764, and Thr or Set amino acid at positions 1651, 1654, or 1657.
