PROBLEM TO BE SOLVED: To provide a method for producing a recombinant protein, which uses a plant and whereby the recombinant protein can be collected easily, to provide the recombinant protein of which the activity can last steadily, and to provide a method for introducing a protein in a simple manner.SOLUTION: The method for producing the recombinant protein comprises a step of allowing a plant to produce the recombinant protein having an RGD (arginine-glycine-aspartic acid) sequence therein and allowing the recombinant protein to be released outside the plant, and a step of collecting the recombinant protein that has been released from the plant.COPYRIGHT: (C)2013,JPO&INPIT【課題】植物を用いる、回収が簡便な組み換え蛋白質の製造方法の提供。また、活性が安定して持続する組み換え蛋白質の提供。また、簡便な蛋白質導入方法の提供。【解決手段】RGD(アルギニン-グリシン-アスパラギン酸)配列を有する組み換え蛋白質を植物に産生させ、植物体外へ放出させる工程と、当該植物から放出された前記組み換え蛋白質を回収する工程を含む組み換え蛋白質の製造方法。【選択図】図4
