Abstract: The invention provides adenoviral coat proteins comprising various non-native ligands. Further, the present invention provides an adenoviral vector that elicits less reticulo-endothelial system (RES) clearance in a host animal than a corresponding wild-type adenovirus. Also provided by the invention is a system comprising a cell having a non-native cell-surface receptor and a virus having a non-native ligand, wherein the non-native ligand of the virus binds the non-native cell-surface receptor of the cell. Using this system, a virus can be propagated. Further provided by the invention is a method of controlled gene expression utilizing selectively replication competence, a method of assaying for gene function, a method of isolating a nucleic acid, and a method of identifying functionally related coding sequences. Additionally, the invention provides a cell-surface receptor, which facilitates internalization.

Abstract translation: 本发明提供了包含各种非天然配体的腺病毒外壳蛋白。 此外，本发明提供了一种腺病毒载体，其在宿主动物中比相应的野生型腺病毒引起较少的网状内皮系统（RES）清除。 本发明还提供了一种包含具有非天然细胞表面受体的细胞和具有非天然配体的病毒的系统的系统，其中所述病毒的非天然配体结合所述非天然细胞表面受体的非天然细胞表面受体 细胞。 使用该系统可以传播病毒。 本发明进一步提供了利用选择性复制能力的受控基因表达的方法，基因功能测定方法，分离核酸的方法和识别功能相关编码序列的方法。 另外，本发明提供了促进内化的细胞表面受体。
