Channelrhodopsins are a subfamily of retinylidene proteins (rhodopsins) that function as light-gated ion channels. They serve as sensory photoreceptors in unicellular green algae, controlling phototaxis: movement in response to light. Expressed in cells of other organisms, they enable light to control electrical excitability, intracellular acidity, calcium influx, and other cellular processes. Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) from the model organism Chlamydomonas reinhardtii are the first discovered channelrhodopsins. Variants have been cloned from other algal species, and more are expected.
Mitochondrial optogenetics-based gene therapies and their methods of use
PCT designated stageWO2026112440A1Peptide/protein ingredientsMicroencapsulation basedInner mitochondrial membraneNucleic acid sequence
The present disclosure is directed to compositions comprising mitochondrial optogenetics-based gene therapies and their methods of use. In some embodiments, a composition described herein comprises an expression vector comprising a first nucleic acid sequence encoding a channelrhodopsin fusion protein and a second nucleic acid sequence encoding a luciferase protein. In some cases, the first nucleic acid sequence and the second nucleic acid sequence are operably linked to an expression control sequence. In some instances, the channelrhodopsin fusion protein comprises a channelrhodopsin protein linked to an inner mitochondrial membrane-mitochondrial localization signal (IMM-MLS). In some implementations, when the expression vector is expressed, the luciferase protein is localized to the cytosol. In some cases, the IMM-MLS comprises a leading sequence from a mitochondrial inner membrane protein selected from ABCB10, ABCB140, Cytochrome C, and renal outer medullary potassium channel (ROMK).
