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.

L'invention concerne des compositions et des méthodes de production de composants de traduction qui augmentent le nombre d'acides aminés génétiquement codés dans des cellules de vertébrés. Parmi les composants, on trouve des ARNt orthogonaux, des aminoacyl-ARNt synthétases orthogonales, des paires orthogonales d'ARNt/synthétases et des acides aminés non naturels. L'invention concerne également des protéines et des méthodes de production de protéines à acides aminés non naturels dans des cellules de vertébrés. La présente invention concerne en outre des cellules de vertébrés à composants de traduction, par ex., des paires d'aminoacyl-ARNt transférases orthogonales (O-RS) et des ARNt orthogonaux (O-ARNt) et des composants individuels associés, qui sont utilisés dans un mécanisme de biosynthèse de protéines de vertébrés afin d'intégrer un acide aminé non naturel dans une chaîne polypeptidique en développement, dans une cellule de vertébré.
