The paper characterizes and engineers a bistable cnidopsin from a coral that can switch between states using different light wavelengths, showing potential as an optogenetic tool for regulating Gs-signaling.

The paper examines opsin diversification after the teleost whole-genome duplication by analyzing parietopsin paralogs in red piranha and other species, finding slight spectral differences and co-expression patterns.

This study identifies Lys91 as the key residue determining UV sensitivity in vertebrate Opn5, showing its role in spectral tuning and retinal isomer binding.

This paper introduces a safer FISH protocol using low-toxicity reagents, validated in multiple model organisms, enabling sensitive and multiplexed gene detection without proteolytic treatment.

The paper shows that melanotrophs in the pituitary directly sense short-wavelength light, triggering hormone release and UV protection through Opn5m.
