AAV with CamKII promoter driven CreERT2
This AAV expresses CreERT2 driven by a neuron CamKII promoter.
This 1.3 Kb promoter is derived from the murine α-Calcium/calmodulin-dependent kinase II (CaMKII), a gene with expression restricted to excitatory neurons in the neocortex and hippocampus. In cortical neurons, it was shown that the promoter activity of CaMKII(1.3) is about double that of CaMKII(2.4), probably due to some inhibitory element(s).
A mutated form of estrogen ligand-binding domain (ERT2) that binds to synthetic antagonists (such as tamoxifen or its derivative 4-hydroxy-tamoxifen) but not to circulating estrogen, was fused to the Cre recombinase (Cre) to create CreERT2 (also known as “inducible Cre”). When tamoxifen binds to CreERT2, it induces a conformational change of CreERT2, leading to its nuclear translocation, followed by Cre/Lox-mediated recombination.
