We examine detailed G protein selectivity and second messenger signalling of unique Gq-coupled coral opsins and compare them with a representative Gq-coupled opsin, jumping spider Rh1, and Gq-DREADD, hM3Dq. https://doi.org/10.2108/zs24008530 Mar 2025 10:39 +0000at://did:plc:7qlgkpn4tkf4c6dfao5npbpy/app.bsky.feed.post/3lllnp7xhmk2zhttps://bsky.app/profile/yusakai.bsky.social/post/3ldlwfsjhk222Our latest preprint about spectroscopic properties of unique #coral #opsins has been uploaded on bioRxiv.
