A mouse with active αCaMKII is first to the target, but its learning is less flexible and less fine-tuned.
Elgersma
The team created mice lacking two inhibitory phosphorylation sites on αCaMKII. Wild-type αCaMKII is displaced from synapses in part by the phosphorylation, but the mutant protein has an enhanced affinity for synapses. This lowers the threshold for establishing long-term potentiation (LTP)—a synapse-strengthening event associated with learning—probably because it now takes less calcium rushing into the synapse to reach the necessary level of αCaMKII activity.
Initial water-maze learning by the mice was normal. But the mutant mice, unlike wild type, did...
