Peptide inhibitor of the interaction between the C-terminus of the GluR2 (AMPA receptor) subunit and N-ethylmaleimide-sensitive fusion protein (NSF), a protein that regulates AMPA receptor function. Reduces postsynaptic currents in CA1 neurons, AMPA-mediated currents in cultured hippocampal neurons and AMPA receptor surface expression. Control peptide pep4c (Cat. No. 1596) also available.
