Lagman, Bergqvist & Kuraku analysed opsin gene evolution in jawless vertebrates, confirming tandem duplications of visual opsins before the vertebrate radiation.

Another part of this is proven, not just theory: octopus skin has the same light sensing proteins (opsins) as their eyes, and can react to light even with zero input from the brain (research re. 2015.)

But skin only detects brightness, not color, so it doesn't fully solve the mystery on its own! 🧵⬇️

My group at Science has been running a big campaign to engineer new channelrhodopsins.

Excited to share the first results from it today: a suite of highly sensitive new opsins.

We call them "WAChRs".

Everyday indoor office lighting is enough to activate them pretty strongly.

Thrilled to share our new paper in Genome Biology & Evolution! 🌊
We discovered an ocean of opsins in marine zooplankton — unveiling how these animals evolved to sense light across the world’s seas.

SEEING. WITHOUT. EYES.

Opsins are fucking everywhere, folks. And not just light/dark, but colors. All the way down the phylogenetic tree to the roots.

Three studies determined structures and performed complementary modeling and biochemical experiments for human and nonhuman primate opsins, providing molecular insight into how visual pigment absorption and activation kinetics are tuned.

Reintroducing myself as I did this so well the last time (see below 😅)
I'm a biophysicist interested in opsins and their utilization as tools for #neuroscience. Mostly worked with inhibitory opsins, recently optoGPCRs for presynaptic inhibition. Here to get back the bird vibe!

The tuatara and many lizards possess a parietal eye, where non-visual opsins are expressed. Romero & @fsjsouza.bsky.social compared 60+ genomes to study the evolution of non-visual opsins, suggesting a functional role associated with the parietal eye.

Policarpo et al. analyse 535 genomes to study opsin evolution across ray-finned fishes. Visual opsins are more prone to duplications and losses than nonvisual opsins; fish that rely on electroreception show a reduction in both opsin types.

They said protein synthesis was hard to do by hand or something idk

Have you ever tried discovering new opsins

Some of the cells in this fish's brain contain opsins, allowing them to respond to light. But... why? That story and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪
