- 14. A method for treating, or ameliorating a medical condition according to claim 13 wherein the modulator is an antagonist.
- 15. A method for treating, or ameliorating a medical condition according to claim 13 wherein the modulator is an agonist.
- 16. A method of diagnosing a pathological condition or a susceptibility to a pathological condition in a subject comprising the steps of:
(a) determining the presence or amount of expression of the polypeptide of SEQ ID NO:2 in a biological sample; and (b) diagnosing a pathological condition or a susceptibility to a pathological condition based on the presence or amount of expression of the polypeptide relative to a control, wherein said condition is a member of the group consisting of colon cancer, related proliferative condition of the colon, breast cancer, related proliferative condition of the breast, prostate cancer, related proliferative condition of the prostate, lung cancer, related proliferative condition of the lung, renal tumors, and related proliferative condition of the kidney.
