  • Publication number: 20230331790
    Abstract: An object of the present invention is to provide a modified channelrhodopsin having high ion permeability (photoreactivity). The solution is to substitute the third extracellular domain counted from the N-terminal side of three extracellular domains included in a Volvox carteri-derived channelrhodopsin by a corresponding extracellular domain of a Chlamydomonas reinhardtii-derived channelrhodopsin-2.

  • Publication number: 20210347831
    Abstract: An object of the present invention is to provide a modified channel rhodopsin capable of opening and closing an ion channel by irradiation with light at different wavelengths, and/or having high ion permeability (photoreactivity). The solution is to substitute a C-terminal region of a channel rhodopsin obtained by substituting an N-terminal region of a Volvox carteri-derived channel rhodopsin by an N-terminal region of a Chlamydomonas reinhardtii-derived channel rhodopsin-1, by a C-terminal region of a Chlamydomonas reinhardtii-derived channel rhodopsin-2 or a C-terminal region of a Tetraselmis striata-derived channel rhodopsin.

  • Patent number: 10924719
    Abstract: Provided is a head-mounted video presentation device which has a visible light wavelength conversion and is designed for a user having degraded sensitivity to a first wavelength band as a part of a visible light wavelength band as compared with a second wavelength band as the remaining part of the visible light wavelength band.

  • Patent number: 8754048
    Abstract: Disclosed is a Volvox carteri-derived light-receiving channel rhodopsin with an improved expression efficiency on a cell membrane. Specifically disclosed is a modified Volvox carteri-derived light-receiving channel rhodopsin protein. The protein is modified to contain an N-terminal region of Chlamydomonas reinhardtii-derived channel rhodopsin-1 at the N-terminal of the Volvox carteri-derived light-receiving channel rhodopsin protein, wherein the N-terminal region is involved in cell membrane-localized expression and contains no transmembrane domain of the Chlamydomonas reinhardtii-derived channel rhodopsin-1.
