Photoreceptor current and photoorientation in chlamydomonas mediated by 9-demethylchlamyrhodopsin.

Biophysical journal - 1 Nov 2001

Abstract excerpt

Green flagellates possess rhodopsin-like photoreceptors involved in control of their behavior via generation of photocurrents across the plasma membrane. Chlamydomonas mutants blocked in retinal biosynthesis are "blind," but they can be rescued by the addition of exogenous retinoids. Photosignaling by chlamyrhodopsin regenerated with 9-demethylretinal was investigated by recording photocurrents from single cells...
