  • Patent number: 10851403
    Abstract: Disclosed is a cyclin-dependent kinase substrate including a polypeptide that contains an amino acid sequence represented by formula (1): R1—P (wherein R1 represents a serine residue or a threonine residue, P represents a proline residue, “—” represents a single bond, and the left side represents the N-terminal side), and satisfies the following (a1) and/or (b1): (a1) the second amino acid residue counting from the proline residue toward the N-terminal side in the formula (1) is an aromatic amino acid residue, and/or (b1) at least two amino acid residues from the proline residue toward the C-terminal side in the formula (1) are acidic amino acid residues.

  • Publication number: 20160289726
    Abstract: Disclosed is a method of producing a glycoprotein, the method including the steps of: introducing a gene encoding a desired protein and a gene encoding an antibody that inhibits a decomposing enzyme preventing formation of a desired complex-type sugar chain in the desired protein into an insect organism or insect cells; and obtaining a desired protein having a desired complex-type sugar chain from the insect organism or insect cells obtained in the introduction step.
