Pep2m
Pep2m is a peptide receptor inhibitor. Pep2m inhibits the interaction between the C-terminus of the AMPA-type glutamate receptor (GluA2) subunit and N-ethylmaleimide-sensitive fusion protein (NSF). Pep2m prevents synaptic long-term depression (LTD). Pep2m can reduce postsynaptic currents in neurons, AMPA-mediated currents in cultured hippocampal neurons, and AMPA receptor surface expression[1][2][3][4][5].

Biological Activity
|
AMPA Receptor |
Pep2m reduces EPSC amplitude and blocks LTD in CA1 pyramidal cells of hippocampal slices by reducing the number of functional AMPARs[1].
Pep2m reduces the current response to locally applied AMPA in cultured hippocampal neurons[2].
Pep2m reduces the frequency of recorded AMPA-miniature excitatory postsynaptic currents (mEPSCs) in the presence of tetrodotoxin (TTX)[2].
Pep2m reduces the surface expression of AMPA receptors containing AMPA-type glutamate receptors (GluR2), but does not reduce the surface expression of NMDA receptors and the ingrowth aggregation of AMPA receptors[2].
Pep2m does not affect basal synaptic transmission and low-frequency stimulation (LFS)-induced LTD in young GluA2 KO mice, and does not affect basal synaptic transmission but restores LFS-induced LTD in mature GluA2 KO mice[3].
Pep2m reduces AMPA-induced radiolabeled norepinephrine ([3H]NA) but not AMPA-induced radiolabeled acetylcholine ([3H]Ach) release[5].
