The present invention is directed to obtaining a protein, which forms a SEA-like domain suitable for structural analysis, and analyzing the structural information thereof for drug development or the like. More specifically, the present invention provides a protein consisting of an amino acid sequence represented by SEQ ID NO :1 or a salt thereof; a protein having an amino acid sequence derived from an amino acid sequence represented by SEQ ID NO: 2 by deletion of 0 to 10 amino acid residues from the N-terminal and deletion of 0 to 10 amino acid residues from the C-terminal and having 120 to 139 amino acid residues, or a salt thereof; a method for manufacturing the proteins or salts thereof; a polynucleotide encoding the proteins or salts thereof; an antibody against the proteins; and a screening method using the proteins or salts thereof.
本发明的目的是获得一种蛋白质,该蛋白质形成适合结构分析的 SEA 样结构域,并分析其结构信息用于药物开发或类似用途。更具体地说,本发明提供了一种蛋白质,它由 SEQ ID NO :1 所代表的氨基酸序列或其盐组成;一种蛋白质,它具有从 SEQ ID NO:2 所代表的氨基酸序列衍生的氨基酸序列的蛋白质或其盐;通过从 N 端缺失 0 至 10 个氨基酸残基和从 C 端缺失 0 至 10 个氨基酸残基而具有 120 至 139 个氨基酸残基的蛋白质或其盐;制造这些蛋白质或其盐的方法;编码这些蛋白质或其盐的多核苷酸;抗这些蛋白质的抗体;以及使用这些蛋白质或其盐的筛选方法。
