Nucleic acid and corresponding protein entitled 151P3D4 useful in treatment and detection of cancer
View Patent ↗A novel gene (designated 151P3D4) and its encoded protein, and variants thereof, are described wherein 151P3D4 exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, 151P3D4 provides a diagnostic, prognostic, prophylactic and/or therapeutic target for cancer. The 151P3D4 gene or fragment thereof, or its encoded protein, or variants thereof, or a fragment thereof, can be used to elicit a humoral or cellular immune response; antibodies or T cells reactive with 151P3D4 can be used in active or passive immunization.
1. An isolated polynucleotide, comprising the nucleotide sequence of SEQ ID NO:2.
2. An isolated recombinant expression vector, comprising a polynucleotide of claim 1 , wherein the vector is a viral vector.
3. The recombinant expression vector of claim 2 , wherein the viral vector is selected from the group consisting of vaccinia, fowlpox, canarypox, adenovirus, influenza, poliovirus, adeno-associated virus, lentivirus, and Sindbis virus.
4. An isolated host cell that contains an expression vector of claim 3 .
5. A composition, comprising the polynucleotide of claim 1 and a pharmaceutically acceptable carrier.
6. A process for producing a protein comprising the amino acid sequence of SEQ ID NO:3 comprising:
culturing a host cell of claim 4 under conditions sufficient for the production of the protein, and
recovering the protein from the culture.
7. The process of claim 6 , wherein the protein is recovered using chromatography.
8. The polynucleotide of claim 1 , consisting of the nucleotide sequence of SEQ ID NO:2.
