Most of the molecular mechanisms contributing to long-term memory have been found to consolidate information within a brief time window after learning, but not to maintain information during memory storage. However, with the discovery that synaptic long-term potentiation is maintained by the persistently active protein kinase, protein kinase Mζ (PKMζ), a possible mechanism of memory storage has been identified. Recent research shows how PKMζ might perpetuate information both at synapses and during long-term memory.
