    摘要: The present invention includes a chimeric protein comprising a VWF protein with D′ domain and D3 domain of VWF, one or more XTEN sequence, and a FVIII protein, wherein the VWF fragment, the XTEN sequence, or the FVIII protein are linked to or associated with each other. The chimeric protein can further comprise one or more Ig constant region or a portion thereof (e.g., an Fc region). A polypeptide chain of a VWF fragment is associated with a FVIII polypeptide chain linked to an XTEN sequence. The VWF fragment polypeptide chain can prevent or inhibit binding of endogenous VWF to FVIII protein linked to the XTEN sequence. By preventing or inhibiting binding of endogenous VWF to FVIII protein, VWF fragment can extend half-life of chimeric protein comprising FVIII protein. The invention includes nucleotides, vectors, host cells, use of VWF fragment, or chimeric proteins.

    摘要翻译: 本发明包括嵌合蛋白,其包含具有D'结构域的VWF蛋白和VWF的D3结构域,一个或多个XTEN序列和FVIII蛋白,其中VWF片段,XTEN序列或FVIII蛋白连接到或相关联 与彼此。 嵌合蛋白可进一步包含一个或多个Ig恒定区或其部分(例如Fc区)。 VWF片段的多肽链与与XTEN序列连接的FVIII多肽链相关。 VWF片段多肽链可以预防或抑制内源性VWF与与XTEN序列连接的FVIII蛋白的结合。 通过预防或抑制内源VWF与FVIII蛋白的结合,VWF片段可以延长包含FVIII蛋白的嵌合蛋白的半衰期。 本发明包括核苷酸,载体,宿主细胞,VWF片段或嵌合蛋白的用途。
