    摘要: It has been believed that promoting the assembly of polysomes composed of many ribosomes attached to mRNA is very effective for highly efficient protein synthesis. However, the mechanism for p180 protein's capability of promoting polysome formation has been yet to be elucidated.The inventors of the present application newly discovered SF3b4 protein as a protein that specifically interacts with the coiled-coil domain of p180 protein, a responsible region for its capability of promoting polysome formation, and which is capable of promoting mRNA localization to an endoplasmic reticulum (ER). The inventors also found that, in cells capable of highly expressing both p180 protein and a protein promoting mRNA localization to an endoplasmic reticulum (ER) (e.g., SF3b4 protein), the mRNA localization to the endoplasmic reticulum can be significantly elevated so that the secretory capacity in cultured cells can be enhanced. Further, the inventors demonstrated that when a particular nucleotide sequence is inserted into an expression plasmid, SF3b4 protein exhibiting protein expression enhancing ability can be localized onto the endoplasmic reticulum membrane, and the mRNA distribution in polysomes can be shifted towards heavier fractions, whereby the secretory capacity in cells can be enhanced.

    摘要: Provided are methods of producing a novel collagen peptide composition, and a DPP-4 inhibitor and antihyperglycemics that comprise the above-mentioned collagen peptide composition. Ginger rhizome-derived enzymes are added to and break down a collagen and/or gelatin solution to generate peptide compositions comprising peptides represented by X-Hyp-Gly (wherein X represents an amino acid residue other than Gly, Hyp, and Pro). The thus obtained collagen peptide composition has a high DPP-4 inhibitory activity and an excellent antihyperglycemic effect.

    摘要: Provided is a collagen structure characterized by: comprising collagen fibers of 1 to 5 μm in average diameter; and has a water content of 0 to 15 (w/w)% and a collagen density of 50 to 800 mg/cm3. After generating collagen fibers by neutralizing an acidic collagen solution, the resulting solution is subjected to filtration or the like to form crude collagen fibers having a collagen concentration of 12 to 50 (w/v)%. The thus obtained crude collagen fibers are molded into a prescribed shape and then dried, thereby the collagen structure can be produced. Since the collagen structure is produced using, as raw material, collagen fibers that are formed by association of collagen molecules, the collagen structure has excellent cell infiltration property. Further, since the collagen density of the collagen structure is equivalent to that of in vivo collagen tissue, the collagen structure exhibits excellent tissue regeneration capacity when filled into a defective part in vivo. Therefore, the collagen structure can be preferably used as an artificial material for regenerative medicine and the like.
