abstract = {Optogenetics is a powerful approach in neuroscience
research. However, other tissues of the body may benefit
from controlled ion currents and neuroscience may benefit
from more precise optogenetic expression. The present work
constructs three subcellularly-targeted optogenetic
actuators based on the channelrhodopsin ChR2-XXL, utilizing
5, 10, or 15 tandem repeats (TR) from mucin as N-terminal
targeting motifs and evaluates expression in several
polarized and non-polarized cell types. The modified
channelrhodopsin maintains its electrophysiological
properties, which can be used to produce continuous membrane
depolarization, despite the expected size of the repeats.
This work then shows that these actuators are subcellularly
localized in polarized cells. In polarized epithelial cells,
all three actuators localize to just the lateral membrane.
The TR-tagged constructs also express subcellularly in
cortical neurons, where TR5-ChR2XXL and TR10-ChR2XXL mainly
target the somatodendrites. Moreover, the transfection
efficiencies are shown to be dependent on cell type and
tandem repeat length. Overall, this work verifies that the
targeting motifs from epithelial cells can be used to
localize optogenetic actuators in both epithelia and
neurons, opening epithelia processes to optogenetic
manipulation and providing new possibilities to target
optogenetic tools.},
