Self-regenerating opsin from reef-building coral

Yusuke Sakai, Yasushi Imamoto, Shino Inukai, Yuri Tominaga, Tomohiro Sugihara, Takahiro Yamashita, Kota Katayama, Yukiya Kakeyama, Ririka Oka, Erika Okuno, Makoto Iwasaki, Hideki Kandori, Mitsumasa KOYANAGI, Akihisa Terakita

This paper identifies a coral opsin, AtAntho2c, that can autonomously regenerate its inactive state through thermal isomerization of retinal, enabling repeated light responses without exogenous retinal.

Coral anthozoan-specific opsins employ a novel chloride counterion for spectral tuning

Yusuke Sakai, Saumik Sen, Tomohiro Sugihara, Yukiya Kakeyama, Makoto Iwasaki, Gebhard F. X. Schertler, Xavier Deupí, Mitsumasa Koyanagi, Akihisa Terakita

This study identifies a novel chloride counterion mechanism in coral opsins that stabilizes the Schiff base proton, enabling light sensitivity without a traditional counterion residue.
