abstract |
The present invention relates to the identification of a binding between NMDA receptor (NMDA-R) subunits and a protein tyrosine phosphatase (PTP), e.g., PTPL1. The present invention provides methods for screening a PTP agonist or antagonist that modulates NMDA-R signaling. The present invention also provide methods and compositions for treatment of disorders mediated by abnormal NMDA-R signaling. The present invention further provides methods for isolating PTPL1 from a biological preparation. |
