Fish genomes provide novel insights into the evolution of vertebrate secretin receptors and their ligand

Highlights • SCTR a newly identified member of the Class 2 B1 GPCR family in ray-finned fish. • Fish SCTR shares conserved sequence and gene environment with the tetrapod gene. • SCTR is an orphan receptor in ray-finned fishes. • SCT exists in holocephalian and lobe-finned fishes but was lost in ray...
