Interaction of nmda receptor with protein tyrosine phosphatase

摘要

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 PTPL1 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.
