Abstract
This invention provides compositions and methods for producing translational components that expand the number of genetically encoded amino acids in vertebrate cells. The components include orthogonal tRNA'"'"'s, orthogonal aminoacyl-tRNA synthetases, orthogonal pairs of tRNA'"'"'s/synthetases and unnatural amino acids. Proteins and methods of producing proteins with unnatural amino acids in vertebrate cells are also provided. The present invention provides vertebrate cells with translation components, e.g., pairs of orthogonal aminoacyl-tRNA synthetases (O-RSs) and orthogonal tRNA'"'"'s (O-tRNA'"'"'s) and individual components thereof, that are used in vertebrate protein biosynthetic machinery to incorporate an unnatural amino acid in a growing polypeptide chain, in a vertebrate cell.

27. A vertebrate cell comprising an orthogonal aminoacyl-tRNA synthetase (O-RS), a tRNA encoded by SEQ ID NO:
- 87 or SEQ ID NO;
88, an non-natural amino acid, and a nucleic acid that comprises a polynucleotide that encodes a polypeptide of interest, wherein the polynucleotide comprises a selector codon that is recognized by the tRNA, wherein the O-RS preferentially aminoacylates the tRNA with the non-natural amino acid in the vertebrate cell, and wherein the cell produces the polypeptide of interest in the presence of the non-natural amino acid.
- 87 or SEQ ID NO;
-
31. A method of producing in a vertebrate cell at least one protein comprising at least one non-natural amino acid, the method comprising:
-
growing, in an appropriate medium, a vertebrate cell that comprises a nucleic acid that comprises at least one selector codon and encodes the protein;
wherein the medium comprises an unnatural amino acid and the vertebrate cell comprises;a tRNA having a nucleotide sequence set forth in SEQ ID NO;
87 or SEQ ID NO;
88 that functions in the cell and recognizes the selector codon; andan orthogonal aminoacyl tRNA synthetase (O-RS) that preferentially aminoacylates the O-tRNA with the unnatural amino acid. - View Dependent Claims (32, 33, 34, 35, 36, 37)
