    • An isolated polypeptide containing (i) an immunogenic fragment of an RNR subunit (SEQ ID NO: 1 or 15) spanning Y162 or Y369 of SEQ ID NO: 1, or Y124 or Y331 of SEQ ID NO: 15, or (ii) a mutant fragment of SEQ ID NO: 1 or 15 in which at least one of the aforementioned Y residues is replaced by a non-tyrosine residue. Disclosed are related nucleic acids, expression vectors, host cells, reconstituted RNR enzymes, preparation methods, and compound screening methods. Also disclosed are RNAi agents for inhibiting expression of a gene encoding SEQ ID NO: 1 or 15. Within the scope of this invention are methods of treating a cell proliferation-associated disorder.
    • 一种分离的多肽,其包含(i)跨越SEQ ID NO:1的Y162或Y369或SEQ ID NO:15的Y124或Y331的RNR亚基(SEQ ID NO:1或15)的免疫原性片段,或(ii) SEQ ID NO:1或15的突变体片段,其中至少一个上述Y残基被非酪氨酸残基替代。 公开了相关的核酸,表达载体,宿主细胞,重建的RNR酶,制备方法和化合物筛选方法。 还公开了用于抑制编码SEQ ID NO:1或15的基因表达的RNAi剂。在本发明的范围内,是治疗细胞增殖相关病症的方法。
