Invertebrate Bile Acid‐Sensitive Ion Channels and Their Emergence in Bilateria

The FASEB Journal, Volume 39, Issue 8, 30 April 2025.
This graphical abstract presents the evolutionary distribution and functional characteristics of bile acid‐sensing ion channels (BASICs) across bilaterians. A phylogenetic tree illustrates the presence of BASICs in diverse groups, extending beyond previously established mammalian findings.
