Patent number: 8241626Abstract: Described is a novel family of cell surface serpentine transmembrane antigens. Two of the proteins in this family are exclusively or predominantly expressed in the prostate, as well as in prostate cancer, and thus members of this family have been termed “STEAP” (Six Transmembrane Epithelial Antigen of the Prostate). Four particular human STEAPs are described and characterized herein. The human STEAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins. The prototype member of the STEAP family, STEAP-1, appears to be a type IIIa membrane protein expressed predominantly in prostate cells in normal human tissues. Structurally, STEAP-1 is a 339 amino acid protein characterized by a molecular topology of six transmembrane domains and intracellular N- and C-termini, suggesting that it folds in a “serpentine” manner into three extracellular and two intracellular loops.Type: GrantFiled: October 3, 2006Date of Patent: August 14, 2012Assignee: Agensys, Inc.Inventors: Rene S. Hubert, Arthur B. Raitano, Douglas Saffran, Daniel E. H. Afar, Steven Chappell Mitchell, Mary Faris, Aya Jakobovits

Four particular human STEAPs are described and characterized herein. The human STEAPs exhibit a high'degree of structural conservation among them but show no significant structural homology to any known human proteins. STEAP-2 is a 454 amino acid protein characterized by a predicted molecular topology of six transmembrane domains and intracellular N- and C-termini, suggesting that it folds in a “serpentine” manner into three extracellular and two intracellular loops.Type: GrantFiled: January 6, 2004Date of Patent: May 24, 2011Assignee: Agensys, Inc.Inventors: Rene S.

Patent number: 7892548Abstract: A novel gene (designated 121P1F1) and its encoded protein are described. While 121P1F1 exhibits tissue specific expression in normal adult tissue, it is aberrantly expressed in multiple cancers including prostate, bladder, kidney, brain, bone, cervical, uterine, ovarian, breast, pancreatic, stomach, colon, rectal, leukocytic, liver and lung cancers. Consequently, 121P1F1 provides a diagnostic and/or therapeutic target for cancers, and the 121P1F1 gene or fragment thereof, or its encoded protein or a fragment thereof used to elicit an immune response.Type: GrantFiled: December 7, 2007Date of Patent: February 22, 2011Assignee: Agensys, Inc.Inventors: Pia M. Challita-Eid, Rene S. Hubert, Steven Chappell Mitchell, Arthur B. Raitano, Mary Faris, Daniel E. H. Afar, Aya Jakobovits

Four particular human STEAPs are described and characterized herein. The human STEAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins. The prototype member of the STEAP family is STEAP-1, which appears to be a type IIIa membrane protein. STEAP-1 is a 339 amino acid protein. STEAP-1 protein expression is maintained at high levels across various stages of prostate cancer. Moreover, STEAP-1 is highly over-expressed in certain other human cancers.Type: GrantFiled: May 28, 2004Date of Patent: June 1, 2010Assignee: Genentech, Inc.Inventors: Daniel E. Afar, Rene S.

Patent number: 7582448Abstract: A novel gene (designated 84P2A9) and its encoded protein is described. While 84P2A9 exhibits prostate and testis specific expression in normal adult tissue, it is aberrantly expressed multiple cancers including prostate, testis, kidney, brain, bone, skin, ovarian, breast, pancreas, colon, lymphocytic and lung cancers. Consequently, 84P2A9 provides a diagnostic and/or therapeutic target for cancers, and the 84P2A9 gene or fragment thereof, or its encoded protein or a fragment thereof used to elicit an immune response.Type: GrantFiled: November 7, 2006Date of Patent: September 1, 2009Assignee: Agensys, Inc.Inventors: Aya Jakobovits, Daniel E.

Patent number: 7351583Abstract: A novel gene (designated PHOR-1) that is highly over-expressed in prostate and other cancers and its encoded protein are described. PHOR-1 is a G protein-coupled receptor with homology to receptors involved in olfaction. PHOR-1 in normal human tissues is restricted to prostate, and this gene is highly over-expressed in prostate cancer as well as in cancers of the kidney, uterus, cervix, stomach and rectum. Consequently, PHOR-1 provides a diagnostic and/or therapeutic target for prostate cancer.Type: GrantFiled: November 16, 2004Date of Patent: April 1, 2008Assignee: Agensys, Inc.Inventors: Arthur B.
