A NOVEL NPG-1 GENE THAT IS DIFFERENTIALLY EXPRESSED IN PROSTATE TUMORS

摘要

The invention provides isolated nucleic acid molecules, designated NPG-1 nucleic acid molecules, which encode polypeptides involved in the modulation of a response in a tumor cell. The invention also provides antisense nucleic acid molecules, expression vectors containing NPG-1 nucleic acid molecules, host cells into which the expression vectors have been introduced, and non-human transgenic animals in which an NPG-1 gene has been introduced or disrupted. The invention still further provides isolated NPG-1 polypeptides, fusion polypeptides, antigenic peptides, and anti-NPG-1 antibodies. Diagnostic, screening, and therapeutic methods utilizing compositions of the invention are also provided.
