    • There are provided a Kringle domain structure, comprising: inducing artificial mutations at amino acid residues except for conserved amino acid residues that are important to maintain the structural scaffold of a Kringle domain; and protein scaffold variants, based on the Kringle domain structure, which modulate the biological activities of a variety of target molecules derived from the protein scaffold library by specifically binding to the target molecules. Also, there is provided a method for constructing homo-/hetero-oligomers which allow multi-specificity binding to multiple targets by the tandem assembly monomeric Kringle domain variants using a linker. Additionally, there is provided a method for preparing multispecific monomers and multivalent monomers by grafting target-binding loops of a Kringle domain variant into non-binding loops of another Kringle domain variant with the same or different target binding specificity. Furthermore, a protein scaffold variant based on the Kringle domain structure that specifically binds to target molecules, DNA encoding the protein scaffold variant, or a method and composition for prevention, detection, diagnosis, treatment or relieving of diseases or disorders, particularly cancers and other immune-related diseases, comprising: administering an effective amount of the related molecule to animals, preferably human.
    • 提供了Kringle结构域结构,其包括:在保留Kringle结构域的结构支架很重要的保守氨基酸残基之外的氨基酸残基处诱导人工突变; 以及基于Kringle域结构的蛋白质支架变体,其通过特异性结合靶分子来调节源自蛋白质支架文库的多种靶分子的生物活性。 此外,提供了一种构建同型/异型寡聚体的方法,其允许使用接头通过串联组装单体Kringle域变体多特异性结合多个靶标。 另外,提供了通过将Kringle结构域变体的靶结合环移植到具有相同或不同靶标结合特异性的另一Kringle结构域变体的非结合环中来制备多特异性单体和多价单体的方法。 此外,基于特异性结合靶分子的Kringle结构域结构的蛋白质骨架变体,编码蛋白质骨架变体的DNA或用于预防,检测,诊断,治疗或缓解疾病或病症,特别是癌症和其他疾病的方法和组合物 包括:将有效量的相关分子给予动物,优选人类。
