Functional and topological diversity of LOV domain photoreceptors

Abstract

Photoreceptor proteins dynamically control many critical physiological processes in response to light across the whole phylogenetic order, including the regulation of circadian rhythms and photosynthesis. We created a comprehensive catalog of the protein architectures and biochemical functions of a ubiquitous class of natural photoreceptors, the light–oxygen–voltage sensitive (LOV) class of flavoproteins, including >4,000 new candidate LOVs, which nearly triples the sequence diversity known to date. Establishing the functional and structural diversity of LOVs will (i) shed light on how organisms adapt to environmental changes, (ii) elucidate the structure–function principles by which common photosensory inputs are transmitted into a multitude of cell signaling events, and (iii) beget novel “optogenetic” tools for light-driven physiological perturbation of cells expressing natural or engineered photoreceptors.
