Homozygotes are viable and fertile. Immunoblots using antibodies against both carboxy- and amino-terminal peptide sequences confirms the absence of wildtype protein in brain tissue. These CaMKKalpha-deficient mice exhibit deficits in context fear during both conditioning and long-term follow-up testing. This is accompanied by impaired activation of other kinases and substrates downstream in the Ca<sup>2+</sup>/calmodulin kinase (CaMK) cascade. Homozygous mice have normal long-term spatial memory formation, cued fear conditioning, long-term potentiation and anxiety-like behavior levels. These mutant mice may be useful in neurological studies involving the CaMK cascade, neuronal gene transcription, synaptic plasticity, contextual fear and long-term memory consolidation.

These <i> Camkk1</i> knock-out mice exhibit deficits in conditioned context fear with impaired downstream Camk4 kinase activation.  They are suitable for use in applications related to neuronal functions.

Typically mice are recovered in 12-16 weeks. Contact Customer Service to place an order or for more information.
