  • Patent number: 10905107
    Abstract: The present invention relates to a mouse (Mus musculus) in which expression and site-specific modification of a target protein is temporally and spatially controlled, and a method for producing the same and the use thereof, and more particularly to a transgenic mouse in which expression of a target protein having a modification attached to a specific position is temporally and spatially controlled as a result of incorporation of an unnatural amino acid. In the mouse according to the present invention, in which site-specific modification of a target protein is temporally and spatially controllable, expression of the target protein having the site-specific modification attached thereto is controllable depending on the timing and/or position of introduction of an unnatural amino acid. Thus, the mouse according to the present invention is useful for studies on the in vivo functions of cellular proteins, various human diseases including cancers and neurodegenerative disorders, new drug discovery, and the like.

  • Publication number: 20200385742
    Abstract: Nucleic acids encoding mutant elongation factor proteins (EF-Sep), phosphoseryl-tRNA synthetase (SepRS), and phosphoseryl-tRNA (tRNASep) and methods of use in site specific incorporation of phosphoserine into & protein or polypeptide are described. Typically, SepRS preferentially aminoacylates tRNASepwith O-phosphoserine and the tRNASep recognizes at least one codon such as a stop codon. Due to the negative charge of the phosphoserine, Sep-tRNASep does not bind elongation factor Tu (EF-Tu). However, mutant EF-Sep proteins are disclosed that bind Sep-tRNASep and protect Sep-tRNASep from deacylation. In a preferred embodiment the nucleic acids are on vectors and are expressed in cells such as bacterial cells, archeaebacterial cells, and eukaryotic cells.

  • Patent number: 10723760
    Abstract: A method for producing a site-specifically modified protein based on new carbon-carbon bond formation is disclosed, including the following three steps (marking, activation, and coupling steps): (a) marking of the modification site by incorporating a specific amino acid into a selected position of a target protein; (b) activation of the marked site; and (c) coupling of various post-translational modification (PTM) moieties or other chemical groups onto the activated site to obtain a site-specifically modified protein. The method for producing a site-specifically modified protein can incorporate desired diverse chemical groups including post-translational modification (PTM) moieties into a designated site in a target protein through a new carbon-carbon bond. Furthermore, the modified protein having a site-specific PTM exhibits the same chemical and functional properties as that of a target protein present in cells.
