Photo-Signa1 Transduction in Motile Cilia Blepharisma.

Abstract

Blepharisma-japonicum and Stentor coeruleus, single cell protozoan ciliates, possess both light intensity- and wavelength-sensitivity. Their light sensor molecules, blepharismin and stentorin, respectively, contain hypericin-derived structures as unique photoreceptor chromophores. Under this grant, we recently elucidated the chemical structures of both blepharismin and stentorin. How these light sensor molecules mediate the intensity- and wavelength-sensitive light-sensory responses in these single cell organisms is still under investigation in this laboratory, results so far strongly suggest that both blepharismin and stentorin initiate their primary photoprocesses via electron transfer.
