title: Algal rhodopsins: phototaxis receptors found at last.
abstract: The discovery of two distinct Chlamydomonas sensory receptors responsible for phototaxis reveals additional diversity among the microbial rhodopsins. Sequence and architecture comparisons among this growing family highlight key components for light-responsive functions.
