D2 Dopamine Receptor and Genes and Associated United States Patents

 

OHSU # 0165

Technology Overview

Researchers at OHSU have cloned the D2 Dopamine receptor, and have developed cell lines containing both the D2 short and long forms, which are useful in studying ligand-receptor interactions, and developing potential drug candidates for treatment of neurological diseases. Currently, the university holds numerous patents covering the gene and protein sequences encoding for this receptor and its use as a target for drug development purposes, as well as methods for preparing labeled or unlabeled species for research and development.

Dopamine receptors have key roles in many processes, including the control of motivation, addiction and fine motor movement, as well as modulation of neuroendocrine signaling. Abnormal dopamine receptor signaling in the central nervous system is implicated in several neuropsychiatric disorders, including Tourette's syndrome, Parkinson's disease, schizophrenia, Attention-deficit hyperactivity disorder, and drug and alcohol dependence. Thus, dopamine receptors are common drug targets for  antipsychotics and psychostimulants.

 

Licensing Opportunity

The D2 short form and D2 long form of the receptor are available for non-exclusive licensing as stable transfectants in HEK cells. They are functional in cAMP assays looking at the inhibition of FSK stimulation.  The receptor is tagged with an M1 Flag epitope and, using antibodies to the epitope, show high levels of expression in immunoflourescence characterization.

 

This technology ID # 0165 covers all uses of the Dopamine D2 receptor under US patents.
