Nucleic acid and corresponding protein entitled 162P1E6 useful in treatment and detection of cancer

A novel gene (designated 162P1E6) and its encoded protein, and variants thereof, are described wherein 162P1E6 exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, 162P1E6 provides a diagnostic, prognostic, prophylactic and/or therapeutic target for cancer. The 162P1E6 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 162P1E6 can be used in active or passive immunization.
