NMDA receptor subunits epsilon 1 (NR2A) and epsilon 2 (NR2B) are substrates for Fyn in the postsynaptic density fraction isolated from the rat brain.

Fyn, protein tyrosine kinase, and its substrates were highly concentrated in the postsynaptic density (PSD) fraction prepared from the rat forebrain. There were a number of Fyn substrates unique to the PSD fraction. One of the major substrates in the PSD fraction was found to be a concanavalin A-binding glycoprotein, PSD-gp180, which is the N-methyl-D-aspartate (NMDA) receptor subunit epsilon 2 (NR2B). Western blotting and immunoprecipitation supported the phosphorylation of epsilon 2 by Fyn. NMDA receptor subunit epsilon 1 (NR2A) was also a substrate for Fyn. These results suggest that Fyn is involved in the modulation of synaptic efficacy through the phosphorylation of synapse-specific substrates such as the NMDA receptor/channel.[1]
