Mice lacking protein tyrosine phosphatase alpha (PTPalpha) exhibited defects in NMDA receptor (NMDAR)-associated processes such as learning and memory, hippocampal neuron migration, and CA1 hippocampal long-term potentiation (LTP). In vivo molecular effectors linking PTPalpha and the NMDAR have not been reported. Thus the involvement of PTPalpha as an upstream regulator of NMDAR tyrosine phosphorylation was investigated in synaptosomes of wild-type and PTPalpha-null mice. Tyrosine… CONTINUE READING
