Research Focus


A novel six-rhodopsin system in a single archaeon:
After four years of intensive study, our lab unveiled a six-rhodopsin photosensory system, the most in microbes, in Haloarcula maris mortui.  The system includes three ion translocating rhodopsins, two sensory rhodopsins and one sensory-like rhodopsin.

描述: 描述: 描述: 描述: Six-rhodopsin from H. marismortui
HmBRI: Light-driven proton outward translocator; Bacteriorhodopsin-like.
HmBRII: Light-driven proton outward translocator; Bacteriorhodopsin-like.
HmHR: Light-driven chloride inward translocator; Halorhodopsin-like.
HmSRI: Phototaxis sensory rhodopsin with a congnate transducer, HmHtrI.  Like those known as SRI.
HmSRII: Photo-repellent sensory rhodopsin with a cognate transducer, HmHtrII. Like those known as SRII.
HmSRM: Sensory-like rhodopsin working with a cognate transducer, HmHtrM. Instead of containing Histidine kinase binding domain found in any transducer associated with sensory rhodopsin, HmHtrM lacks such domain.

GPCR, RGS and G-protein signaling: basic scientific facts and biotechnological studies
Our lab is also working on G-protein related pathways in plant and higer systems. 
A GPCR drug screening system is under developments.

Biomimicry based on Photoreceptors and their associated proteins
Bacteriorhodopsins are light-driven proton translocators.  Biomimicry based on photoreceptors potentially can take advantage of sun light to drive the direct production of bioenergy or indirectly.  Bacteriorhodopsin, Halorhodopsin, Sensory rhodopsins, transducers and F1/Fo ATPase are the candidates.
