A Japanese research group, led by Dr. Yoko Yamagata of the National Institute for Physiological Sciences, has successfully generated a novel kinase-dead mutant mouse of the CaMKIIalpha gene that completely and exclusively lacks its kinase activity. They examined hippocampal synaptic plasticity and behavioral learning of the mouse, and found a severe deficit in both processes. They reported their findings in Journal of Neuroscience on June 10, 2009.
