Promoter Details
CaMKIIa, pyramidal neuron/excitatory neuron promoter, 1293bp.
m C aMKIIa promoter, cloned from the promoter region of mouse calmodulin-dependent protein kinase IIa, is 1.3kb in length and is specifically expressed in excitatory neuronal cells.
Functional Gene Details
OChIEF: ChIEF is a fusion of two proteins, ChR1 and ChR2, with Ile mutated to Val at position 170. The characteristic of this protein is that under long-term illumination, the ratio of plateau current to peak current is large, which means that the channel is less inactivated under illumination and is suitable for long-term stimulation. The mutation of Ile accelerates the closing speed of the channel, making ChIEF suitable for high-frequency stimulation. Karl's laboratory has compared the high-frequency stimulation of ChIEF and hChR2(E123A) in pv (small serum protein) neurons, and the effects are equivalent. OChIEF is a codon-optimized version. The excitation light wavelength is 473nm, suitable for high-frequency light activation.
