Among them, CaMKIIδB and δ9 in the heart, and CaMKIIγ in the nervous system, have emerged as regulators of chromatin dynamics, transcription factor activity, and developmental gene programs.
The supplied web research summary identifies CaMKII as a candidate molecular storage component relevant to synaptic memory.
The transcription factor ΔFosB and the brain-enriched calcium/calmodulin-dependent protein kinase II (CaMKIIα) are induced in the nucleus accumbens (NAc) by chronic exposure to cocaine.

CaMKIIδB and CaMKIIδ9 in the heart and CaMKIIγ in the nervous system have emerged as regulators of chromatin dynamics, transcription factor activity, and developmental gene programs.
In the nervous system, CaMKIIγ contributes to kinase-dependent gene expression and may influence plasticity and disease susceptibility.
CaMKII is required for cocaine-mediated accumulation of ΔFosB in rat nucleus accumbens.
ΔFosB-driven dendritic spine induction on nucleus accumbens medium spiny neurons and increased behavioral responsiveness to cocaine are CaMKII dependent.
ΔFosB and CaMKII are induced in the nucleus accumbens of human cocaine addicts.
CaMKIIα phosphorylates ΔFosB at Ser27, a protein-stabilizing site.
ΔFosB and CaMKII form a cell-type- and brain-region-specific positive feedforward loop that regulates reward circuitry responses to chronic cocaine.
ΔFosB is necessary and sufficient for cocaine induction of CaMKIIα gene expression in vivo, selectively in D1-type medium spiny neurons of the nucleus accumbens shell.
