The present invention discloses a new gene, termed PSMA-like, that is very similar
to the prostate-specific membrane antigen (PSMA) gene and cross-reacts with current
detection methods for PSMA. The present invention also provides for a method of
distinguishing the PSMA and PSMA-like mRNAs and/or proteins for diagnostic and
therapeutic strategies that desire specific targeting of either the PSMA or PSMA-like gene.
