    • The present invention is related to a DNA comprising a nucleotide sequence encoding the following polypeptide (a) or (b): (a) a polypeptide consisting of an amino acid sequence which is identical or substantially identical with an amino acid sequence represented by SEQ ID No. 1 or No. 2, (b) a polypeptide consisting of an amino acid sequence represented by SEQ ID No. 1 or No. 2 in which part of amino acids are deleted, substituted or added, and having substantially the same biological activity as the function of the polypeptide (a). The present invention is further related to an antibody binding to the polypeptide or protein, an anti-cancer agent comprising the antibody, a method of screening a substance that binds to the protein or a peptide fragment thereof, and a polynucleotide having at least 15 bases and hybridizing with the DNA according to the present invention under stringent conditions, and a method of detecting cancer with the use of said polynucleotide. The DNA according to the present invention is a cancer-associated gene, and that it is possible to inhibit cancer by blocking the binding of the present protein to its ligand. Accordingly, the present antibody is used not only in the detection of the present protein, but also as an agent for the treatment or prevention of cancers such as prostatic adenocarcinoma and ovarian carcinoma.
    • 本发明涉及包含编码以下多肽(a)或(b)的核苷酸序列的DNA:(a)由与SEQ ID NO:1所示氨基酸序列相同或基本相同的氨基酸序列组成的多肽 1或2,(b)由SEQ ID No.1或No.2所示的氨基酸序列组成的多肽,其中部分氨基酸被缺失,取代或添加并且具有基本上相同的生物活性 作为多肽(a)的功能。 本发明还涉及与多肽或蛋白质结合的抗体,包含抗体的抗癌剂,筛选与蛋白质结合的物质或其肽片段的方法,以及具有至少15个碱基的多核苷酸 并且在严格条件下与根据本发明的DNA杂交,以及使用所述多核苷酸检测癌症的方法。 根据本发明的DNA是癌相关基因,并且可以通过阻断本发明蛋白质与其配体的结合来抑制癌症。 因此,本发明的抗体不仅用于检测本发明的蛋白质,而且用作治疗或预防前列腺腺癌和卵巢癌等癌症的药剂。
