SIGMA-2 RECEPTOR, METHOD OF SCREENING OF SPECIFIC LIGANDS AND USE OF THE SAME IN DIAGNOSTIC OR THERAPEUTIC METHODS

摘要

The present invention relates to the identification, isolation and characterization of the proteins forming the sigma-2 receptor. The invention further relates to the utilization of said proteins for preparing a screening for the sigma-2 receptor, as well as assay of specific candidate ligands to the use of the ligands for setting up diagnostic assays for tumour tissues and for preparing antitumour drugs. Lastly, the isolated proteins are utilized for producing anti-receptor antibodies, which likewise find employ in the diagnosis and therapeutic treatment of neoplasias.
