Methods and compositions for red-shifted chromophore substitution for optogenetic applications
The present disclosure provides compositions and methods used for optogenetics, wherein the composition comprises an optogenetic device and a retinoid processing enzyme.
1. A composition comprising a vector, the vector comprising a polynucleotide sequence encoding a polypeptide, the polypeptide comprising at least one optogenetic device and a retinoid processing enzyme.
2. The composition of claim 1 , wherein the polypeptide comprises a proteolytic cleavage site between the optogenetic device and the retinoid processing enzyme.
3. The composition of claim 1 , wherein the optogenetic device comprises an optogenetic activator.
4. The composition of claim 3 , wherein the optogenetic activator is ReaChR.
5. The composition of claim 1 , wherein the retinoid processing enzyme is a retinal 3,4-dehydrogenase.
6. The composition of claim 5 , wherein the retinoid processing enzyme is Cyp27c1.
