Abstract:
PROBLEM TO BE SOLVED: To provide compositions and methods related to mRNA translational enhancer elements that are sequence elements capable of promoting cap-dependent mRNA translation.SOLUTION: Provided is a cloning or expression vector comprising a transcription promoter, a polynucleotide sequence coding for a polypeptide having a eukaryotic translation initiation codon operably linked to the transcriptional promoter, a 5' untranslated sequence located between the transcriptional promoter and the eukaryotic translation initiation codon, and a translational enhancer polynucleotide located in the 5' untranslated sequence, the translational enhancer polynucleotide comprising one or more of a plurality of mRNA translational enhancer elements (TEEs) having a particular sequence, their variants, homologs, or functional derivatives. Also provided is a eukaryotic host cell comprising the cloning or expression vector.
Abstract:
PROBLEM TO BE SOLVED: To provide a composition and method for manufacturing a translation ingredient that expands the number of amino acids genetically encoded by an eukaryotic cell.SOLUTION: This is a composition containing a protein. The protein contains at least one of non-natural amino acid and at least one of posttranslational modification. The at least one of posttranslational modification includes the bonding of molecules containing a second reactive group by [3+2] cycloadditions to the at least one of non-natural amino acid containing a first reactive group.

Abstract:
PROBLEM TO BE SOLVED: To provide a therapeutic agent for treating or preventing intracellular bacterial infection or parasitic infection, or a disease caused by an infectious agent such as a virus (e.g., hepatitis). SOLUTION: A method for treating intracellular infection includes the steps of: administering a vector construct which directs expression of at least one immunogenic portion of an antigen derived from an intracellular pathogen; and further administering a protein containing the immunogenic portion of the antigen to a warm-blooded animal to generate an immune response as the result.

Abstract:
PROBLEM TO BE SOLVED: To provide polypeptides derived from tryptophanyl-tRNA synthetase, shorter than polypeptides present in nature, having chemokine action, useful for investigation, diagnosis, prognosis and therapeutic applications and useful for controlling vascular endothelial cell functions, particularly for inhibiting angiogenesis especially intraocular vascularization. SOLUTION: An isolated, water-soluble polypeptide derived from tryptophanyl-tRNA synthetase is useful for inhibiting angiogenesis. The polypeptide consists essentially of the amino acid residue sequence of the figure or its angiogenesis-inhibiting fragment. The isolated polypeptide has a size of no more than about 45 kilodaltons. Methods of use of the polypeptide are also provided. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a new peptide for inducing a cytotoxic T lymphocyte (CTL) response. SOLUTION: The peptide is, for example, a CTL-inducing peptide containing 6-25 amino acids. At least the large majority of the amino acids of the CTL- inducing peptide is homologous to the corresponding part of the sequence V (HBc 140-154 ) [sequence number 7]: Leu-Ser-Thr-Leu-Pro-Glu-Thr-Thr-Val-Val-Arg- Arg-Arg-Gly-Arg.
