Description: Cell-permeable inhibitor of atypical PKC isozyme PKMζ
Alternative Names: z-Pseudosubstrate inhibitory peptide
Purity: ≥95% (HPLC)
Biological Activity for ZIP
ZIP is a novel, cell-permeable inhibitor of protein kinase Mζ (PKMζ), a constitutively active, atypical PKC isozyme involved in LTP maintenance. Selectively blocks PKMζ-induced synaptic potentiation in hippocampal slices in vitro. Reverses late-phase LTP (IC50 = 1 - 2.5 μM) and produces persistent loss of 1-day-old spatial memory following central administration in vivo.
Control Peptide and Biotinylated Peptide also available.
