Patterned rhodopsin expression in R7 photoreceptors of mosquito retina: Implications for species-specific behavior.

29 Sep 2009 Visual perception of the environment plays an important role in many mosquito behaviors. Characterization of the cellular and molecular components of mosquito vision will provide a basis for understanding these behaviors. A unique feature of the R7 ... Read more...

Solid-state NMR and functional studies on proteorhodopsin.

3 Mar 2009 Proteins of the proteorhodopsin (PR) family are found abundantly in many marine bacteria in the photic zone of the oceans. They are colour-tuned to their environment. The green absorbing species has been shown to act as a light-driven proton pump ... Read more...

Isolation and functional characterization of a stable complex between photoactivated rhodopsin and the G protein, transducin.

28 Sep 2008 Transitory binding between photoactivated rhodopsin (Rho* or Meta II) and the G protein transducin (Gt-GDP) is the first step in the visual signaling cascade. Light causes photoisomerization of the 11-cis-retinylidene chromophore in rhodopsin (Rho) ... Read more...
