Ion Selectivity and Competition in Channelrhodopsins [PDF]

open access: yesBiophysical Journal, 2013
Channelrhodopsins are light-gated ion channels of green algae. They are widely used for the analysis of neuronal networks using light in the emerging field of optogenetics. Under steady-state light conditions, the two open states, O1 and O2, mediate the photocurrents with different ion conductance and selectivity.

Non-viral delivery and optimized optogenetic stimulation of retinal ganglion cells led to behavioral restoration of vision [PDF]

open access: yes, 2012
Stimulation of retinal neurons using optogenetics via use of chanelrhodopsin-2 (ChR2) has opened up a new direction for restoration of vision for treatment of retinitis pigmentosa (RP).

Proton transfer pathway in anion channelrhodopsin-1

open access: yeseLife, 2021
Anion channelrhodopsin from Guillardia theta (GtACR1) has Asp234 (3.2 Å) and Glu68 (5.3 Å) near the protonated Schiff base. Here, we investigate mutant GtACR1s (e.g., E68Q/D234N) expressed in HEK293 cells.

Channelrhodopsins: A bioinformatics perspective

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2014
Channelrhodopsins are microbial-type rhodopsins that function as light-gated cation channels. Understanding how the detailed architecture of the protein governs its dynamics and specificity for ions is important, because it has the potential to assist in designing site-directed channelrhodopsin mutants for specific neurobiology applications.
