Catalog Number: 2549
Alternate Names: z-Pseudosubstrate inhibitory peptide
Biological Activity
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 and biotinylated peptides (Cat. Nos. 3215 and 3290) also available.
