Identifies a putative tumor suppressor protein that is expressed almost exclusively in the prostate and prostatic adenocarcinoma. It stains the nuclei in both normal and prostate cancer and along with other prostate-restricted markers and may be valuable to definitely determining prostatic origin in poorly differentiated metastatic carcinomas.
