Description

Pep2m, myristoylated TFA (Myr-Pep2m TFA) is a cell-permeable peptide. Pep2m, myristoylated TFA can disrupt the protein kinase ζ (PKMζ) downstream targets, N-ethylmaleimide-sensitive factor/glutamate receptor subunit 2 (NSF/GluR2) interactions. PKMζ is an autonomously active isozyme of protein kinase C (PKC).

How to use

In Vitro:

Pep2m, myristoylated TFA (10 μM) blocks PKMζ-mediated AMPA receptor (AMPAR) potentiation. Pep2m, myristoylated TFA does not block the increase of PKMζ in the hippocampal slices during long-term potentiation (LTP) maintenance, indicating that blocking NSF/GluR2 interactions do not prevent the induction of PKMζ synthesis. Pep2m, myristoylated TFA blocks NSF/GluR2-mediated AMPAR trafficking, and reverses persistent potentiation at both the strongly stimulates synapses and the weakly stimulats synapses that underwent synaptic tagging and capture.

In Vivo:

Pep2m, myristoylated TFA (10 µg/20 µL) results in an increase in paw withdrawal thresholds (PWTs) on nociceptive responses in the formalin test.
